RE: Generator/Shore Power Work, Battery Power Doesn't

Be more descriptive, what do you mean by “black tune looking things”? Can’t tell by looking at your photo. Its the black tube thing at the bottom of the picture. Its hooked to the silver thing in the corner and hooks to the thing on the right side of the picture. Its almost made of like ceramic. The guy told me its a "Ceramic resistor".

RE: Generator/Shore Power Work, Battery Power Doesn't

https://i.imgur.com/KGq3siDl.jpg I got the converter part out. Where do I go from here? When I got the battery charge board from Progressive, they also sent me some of the black tube looking things because they occasionally go out also, do I try and replace that?

RE: Generator/Shore Power Work, Battery Power Doesn't

Just wondering if the OP has successfully fixed his charger/convertor problem? So unfortunately not. I haven't had time lately due to having our first kid, the motorhome has been put on the back burner for a minute. I'm working on getting a new battery for it. So when I took the old battery out, I decided to hook up shore power and see if I got 12 volts on any of the posts I was taking reads off of before. Because I figured if it was converting correctly that I should be able to see at those posts if it is or not. Is that a stupid test? It made sense in my head but don't know if it makes sense or not. But the results were 8 volts on one side and then shore power on the other side. Does that show anything or not? I was working on pulling out the converter since I'm pretty sure thats my issue but haven't gotten around to finishing it since I'm a lot more busy with other things now. Thats what my gut tells me the issue is but this thing has me thinking all sorts of different things so who knows!

RE: Generator/Shore Power Work, Battery Power Doesn't

BrocNeal, OK I guess I can assume the replacement charger board did not fix the problem. Your system may have only one SCR or maybe two SCRs wired in parallel. A SCR is a 3 terminal device, an input terminal (anode), an output terminal (cathode) and a gate terminal. When connected to shoreline power, measure the DC voltage to ground on all three SCR terminals. The output terminal should be the same as your house battery voltage, 12.48 volts per a previous measurement you made. The voltage at the input terminal should be I believe around 18 volts, the same as the output voltage from the transformer module you previously measured. The voltage on the gate terminal will tell the story. If it is more than 1.0 volt higher than the SCR’s output terminal, then that or both SCRs are toast. No it didn't unfortunately. So im working on pulling the converter box out so I can check the SCR and everything. That's turned out to be quite the job but I'll get it. Once I get that out I'll be able to test it much easier than where its currently at. If the SCR is bad, is that something you can replace easily? Like just go buy a new one or do I have to find this exact same one or do I then need to find a replacement box as a hole? It looks intimidating not gonna lie.

RE: Generator/Shore Power Work, Battery Power Doesn't

BrocNeal, OK, look at the schematic on page 20 of the maintenance manual. You will notice the SCR in the upper left corner of the schematic. The SCR acts like an electronic on/off switch. How the system works is that the battery charger PC board monitors the charge level of the house battery(s) by inputting the current battery voltage level onto the red wire going into the board. The board analyzes this voltage level and determines if further charging of the battery(s) is necessary, If so, the board sends a signal to the SCR's gate terminal via the green wire shown which then turns on the SCR connecting the output of the DC voltage output of the transformer module via the blue wire shown into the SCR and since the SCR is now turned on the SCR now conducts that DC voltage to the output terminal of the SCR which connects to the battery9s) via the orange wire. Actually, the SCR is never fully turned off. The charge board varies the signal to the SCR gate via the green wire on a pulse basis with the turn on pulse being longer when the battery(s) are heavy discharged to a turn on pulse being shorter when the batter(s) are fully charged and only requiring a low level maintenance charge level. If this SCR was destroyed when the former owner connected up the battery(s) reversed polarity, of course the charge board would be trying to turn on the SCR to try and make it conduct a charge current to the battery(s) to no avail. Okay that makes sense. I'll have to look a little more into that. I just got home from a vacation so that's why I haven't been on here. I did have a chance to crawl underneath the motorhome and didn't find any fuses or circuit breakers. I did redo some grounds because they looked pretty rough. Still no luck on fixing the problem. I dont remember if I already said this, but I got an outlet tester and plugged it in to every outlet when plugged in to shore power/generator and they all say "Hot/Neutral Reversed". So I assume that definitely is part of my issue. I dont know what that means but its good to know. Still doesn't make any sense that the lights would work when I brought it home and then I change out the circuit breakers in the house battery box and get the lights working off the battery that the issue would reverse into what it is now. But I'll get it, there's only one way to learn!

RE: Generator/Shore Power Work, Battery Power Doesn't

BrocNeal, well your replacement battery charger PC board is on the way to you. Sure hope this fixes the no charging problem. If not the only other thing that I can think of is a failure of the S.C.R. as shown on pages 3, 17 & 20 of the Service Manual. I can believe that this component may have been destroyed if as you said the former owner of your rig connected up the house battery(s) reversed polarity. The SCR is mounted in a heat sink as shown on page 17 in the transformer module. Leads to it would have to be unsoldered and then the part would then have to be unbolted to remove it. Then hopefully the SCR has brand and P/N on it in order to purchase a replacement. That's what I'm hoping, I don't know if it'd fix the no lights when hooked up to shore power but I hope so. I know I called progressive dynamics and that was what the guy said he would think the problem would be after I told him my issues, so let's hope for the best! Now what exactly is the SCR and what does it do? It sounds complicated but the motorhome is from 1979 so I wouldn't think it would be too crazy!

RE: Generator/Shore Power Work, Battery Power Doesn't

BrocNeal, Just for my own interest I contacted Progressive Dynamics about availability of repair of battery charger PC boards or replacements. I have copied the email I sent and the email I got back from Andy at the factory below. -----Original Message----- From: William R Hemme Sent: Thursday, July 23, 2020 2:03 PM To: service@progressivedyn.com Subject: PD734Q Repair Does Progressive Dynamics still repair or have replacement battery charger PC boards for the PD734Q RV power center? Bill Hemme -----Return Message----- Andy Giesen RE: PD734Q Repair To: Bill Hemme Hello, We do not repair the charger boards. I found a 6 pin charger board in our old inventory. I am not even positive it works as I have no way of testing now. It should work though. I am happy send it out to you at no charge I will put it in the mail and send it to the address on Elmwood dr. Let me know how it works for you. Andy I emailed Andy back to not send the board to me and I would contact you about it. Please contact Andy at his email address agiesen@progressivedyn.com if you want to receive this board free of charge. This of course assumes that your board is the model with a connector that has slots for 6 pins. Best I can tell from your photos is that describes your board. Sorry I'm just getting back to you, I had a chance to email him yesterday and I haven't heard anything back yet, so he may have already sent it to you. But either way, thank you for reaching out for me, you're awesome! I'm really thinking that's my issue so hopefully I hear back from him!

RE: Generator/Shore Power Work, Battery Power Doesn't

Well that means to me if your voltmeter connections were correct that the 22 vdc coming into the battery charger PC board would appear to be somewhat normal so the transformer module seems to be working OK. However the 9.4 to 11.5 vdc coming out of the charger board is way too low to cause any charge to your batteries. Also if there was any significant battery charging current coming out of the charger board, that LED indicator light as shown in the schematic on page 20 of the manual would be illuminated which it isn’t. My conclusion again is that the charger PC board is toast. That's kinda what I'm starting to think. So let me see if I understand the board correctly (This is my first RV and I'm only 24 so I'm still learning, but doing my best). I assume just by looking at it, the power comes in from the top 1 or 2 wires in the plug, goes through the board, and then goes out through the bottom 3 wires into the relay and everything?

RE: Generator/Shore Power Work, Battery Power Doesn't

So mine doesnt have a blue wire going to the charge board. But I don't have 16 going into it anywhere. Then the 2 orangeish wires I have going anywhere go to a circuit breaker and I have 12.48 going to both posts on that. Looking at the manual, I should have a light doing something if the charger was working. And I have no light whatsoever no matter what it's doing. So I dont know if that means the charger is bad and that's my problem with my lights or what. BrocNeal, Both pages 3 and 20 of the service manual show a blue wire going into the battery charger PC board. Why you don't or can't find that blue wire is a puzzle. However, at this point I believe the 14.28 vdc you are measuring on the orange wires on both terminals of the Auto Breaker is actually the voltage coming from your batteries and not the voltage being generated by the battery charging circuit. So, do this next. Temporarily disconnect all leads going to the positive terminals of of your batteries. Then connect up to shoreline power (you won't now be abe to start your generator). Then measure the voltage on the two orange wires and post what it is. Then please find the blue wire (or what ever the color is in your system) that connects the blue wire input to the battery charger pc board as shown on page 20 of the manual. Then measure that voltage going into the battery charger board. If you have significant voltage there but no voltage on the orange wires then that tells me that your battery charger pc board is bad and you need to find a replacement board. https://i.imgur.com/mT1Hufwl.jpg So I did as you said to and disconnected the batteries and took voltage readings after I did that. So, the two orange posts read between 9.4-11.5 without the batteries hooked up. Then the wires going into the charge board, 4/5 read the same 9.4-11.5. Then the top wire, which ended up being white, read 22.8. I have the picture attached that show the readings on the relay that switches power over as well. Then hooked the batteries back up and they read the same as before.

RE: Generator/Shore Power Work, Battery Power Doesn't

https://i.imgur.com/mHT2UCDl.jpg https://i.imgur.com/gYjqX2Gl.jpg So I Went out and tested voltage again and found this While plugged into shore power. I thought it was weird and then after a few it jumped up to the 14.28 on one side that it was before, and then it stopped and never went back up to that number and would lie somewhere between .15-.5. That definitely doesn't seem normal to me. Then after it dropped I tested it again and the center post on the battery side shows a negative like something is crossed or something if that makes sense. Its only done that when the voltage dropped, but all 4 other posts show a positive charge. I haven't messed with any of the wiring in there and it doesn't look like anyone has. So am I crazy?

RE: Generator/Shore Power Work, Battery Power Doesn't

BrocNeal, Things to check now that you have the service manual to reference. 1) Using a voltmeter against ground, check the voltage on the blue wire going to the battery charger board when either plugged into shoreline power or with generator running. If it reads around +16 vdc or so that is good showing that the dc output from the transformer module is good. 2) Then check for dc voltage on the two orange wires going to the Auto Breaker. You should have around +14 vdc on both orange leads. If no dc voltage on either orange lead, then the battery charger pc board is bad an must be replaced, If dc voltage exists on one orange lead but not the other, than the Auto Breaker is open and must be replaced. So mine doesnt have a blue wire going to the charge board. But I don't have 16 going into it anywhere. Then the 2 orangeish wires I have going anywhere go to a circuit breaker and I have 12.48 going to both posts on that. Looking at the manual, I should have a light doing something if the charger was working. And I have no light whatsoever no matter what it's doing.

RE: Generator/Shore Power Work, Battery Power Doesn't

In this picture are three arrows. What color is the wire that the green arrow is pointing to? Where does that wire after it goes through the hole on the left? The red and blue arrows are pointing to wire connections at the back of the charge sentinel light. If you plug in shore power how many volts are on the red arrow? While still plugged in to shore power how many volts are on the blue arrow? https://i.imgur.com/8i9LQi1l.jpg "border=0" https://i.imgur.com/m3zZPvb.pngClick For Full-Size Image. So the wire is just a copper wire that ends on a board with about 8 other wires on it. Then the Red and blue wire both read 12.57 plugged in

RE: Generator/Shore Power Work, Battery Power Doesn't

Understanding better how the transformer works Here's a few more things to check. Start with the easy things. There is a yellow button on the general purpose breaker. I'm wondering if it's a GFCI. If you plug into shore power and press that yellow button does anything suddenly start working? On the front of the panel is a charge sentinel light. When plugged into shore power does that light do anything? Does the light come on, on and blink fast, on and blink slow, or stay off? I tried the yellow button and nothing happened. Then I checked the light and it wasn't lit up or anything.

RE: Generator/Shore Power Work, Battery Power Doesn't

If you force the relay contacts together with additional manual force and everything starts working then there is your problem. The relay contacts are dirty and must be cleaned and dressed with a relay file. That should restore the proper operation of that relay. The problem is, the relay contacts sit in the down position and nothing happened when i pushed it down, the lights only came on when i pushed the relay contact up. But then I realized when I unplugged it from shore power, it clicked up into the up position. So I think I was just activating the battery power on top of the shore power I think.
BrocNeal 07/18/20 07:06pm Class C Motorhomes
RE: Generator/Shore Power Work, Battery Power Doesn't

So I just tested it for a click. It does click like it's supposed to when you plug it in. But the voltage doesnt transfer over like it's supposed to. But I checked the contact points and they looked okay, but I thought I'd try and manually push it up to touch the other contact and everything started working. Then right as I stop pushing it to touch the contact the lights go off but the ac and everything else works. Is that my problem or is that just making the battery and shore power work at the same time?

RE: Generator/Shore Power Work, Battery Power Doesn't

If no click then I think you have a bad diode and are going to wind up having to replace the whole unit. In order to work the relay needs a ground to energize the coil and move the arm. My thinking is that the 2.61V wire is supposed to go to ground and activate the relay. But there a bad diode (basically a one way switch) allowing voltage to leak back up the ground and keep the relay open. Inspect the little circuit board that the 2.61v wire is connected to. Look at both sides. Are there any dark brown or burnt spots on the board? If possible can you post a close up picture of both sides of the board? So I've definitely heard a click when I turn on the generator, but I have to wait for someone's help to test if it clicks on or off when plugged into shore power, I'm pretty sure it doesn't but I'll make sure. So by replacing the whole unit, do you mean the little blue automatic output relay or the entire progressive power system?

RE: Generator/Shore Power Work, Battery Power Doesn't

First, let me be clear....I am not familiar with your Progressive Dynamics fuse panel / power distribution panel. But...... It appears to have a huge relay or power transfer switch integrated inside it, the devise with the blue circle. With the panel open as you have pictured, plug your RV into 110V and see if it clicks into one position or another. Your hand written voltage readings indicate otherwise, but it just might involve 110V under certain conditions. Who knows what the RV industry practiced back in 1979. Take voltage readings on all the terminals under these 4 different power-support conditions. - when plugged into shore power - with the generator running - with the main engine running - with nothing running. Unrelated to that....... If your Progressive Dynamics power distribution panel does not have a big transformer, than you must have a separate 110V to 12V power converter located somewhere else inside the motor home, maybe behind that Progressive Dynamics power distribution panel. Everything I am saying here is subject to great scrutiny. So I just took the readings you said. The generator and shore power both resulted in the same readings that I posted yesterday. Then I just posted pictures of the new readings of the battery and van power as well.

RE: Generator/Shore Power Work, Battery Power Doesn't

Alright so I didn't quite dig all the way into it as I didn't have a ton of time. But I found this and it doesnt seem right. I have 14.28 on 3 posts and on the opposite side I've got 12.66 on one (I threw a charger on the battery the other day) and 2.61 on the other. Is this the converter? It didn't seem right to me so I figured I'd stop and get your guys opinions before I jumped in any further. It appears to be messed up, right?
