RE: Onan marquis 5500 generator

OP: You might want to get yourself a Kill-O-Watt meter: https://www.amazon.com/P3-P4400-Electricity-Usage-Monitor/dp/B00009MDBU You just plug it into any electrical outlet and it will tell you if you what kind of volts and hertz you are getting from your generator into your RV.

RE: Thermostat Fan Speed switch doesn't work, LONG

What was odd to me was the furnace came on at a very high speed, high enough that as my wife walked over floor register, her nightgown did a MM thing by blowing up around her knees. I don't know the cause, but this is the only way you should operate your furnace from now on. :) Steve

RE: Need help replacing charging circuit solenoid.

When the rocker switch is in "OFF", the solenoid works from the run circuit and key. Nope. When the rocker switch is in the middle position (it is 3-way), then the solenoid does not work at all. Rocker must be in MOM or DUAL to energize solenoid. In key postion "ON" (but not in "START") you are already in "DUAL" (at least in my rig which has no rocker switch) If you have no rocker switch, then I don't know how yours works. With the rocker, it must mean you don't get "DUAL" just from powering the solenoid, you need to push "DUAL" too. But why should that mean the rocker needs to get any power from the run circuit to pass along to the solenoid, which is already in the run circuit? The rocker is a 3-way switch. In the middle, it's off. When locked in Dual, it routes vehicle run power to the solenoid. When held in MOM, it routes house battery power to the solenoid. The rocker switch will "stick" in the middle position (off), and in DUAL. It's spring loaded in MOM, so you have to hold it in MOM. Does that mean the rocker itself needs 12v power to go from "OFF" to either MOM or DUAL? 12V power is what the rocker switch diverts to the solenoid. It's either getting 12V power from the house battery (MOM), or it's getting 12V power from the engine battery (DUAL) when key is in RUN. All the 3-way switch is doing is letting you choose the power source for the solenoid. That's it. DUAL picks up power from the engine battery (if ignition is in RUN). MOM picks up power from the house battery. And of course the middle position is "OFF".

RE: Need help replacing charging circuit solenoid.

enblethen is right. Hopefully this will put the nail in it: https://i.imgur.com/FZEL8Gfl.png "Battery Changeover" on the schematic is the rocker switch. I have labeled MOM and DUAL. The center common wire goes to the Charging Solenoid (they call it Battery Solenoid). When in MOM, it's pretty simply - the Aux Battery (House Battery) is routed to the Charging Solenoid and gangs the batteries together. Done deal. When it's in DUAL, power comes from the "Fuse Panel". This is a 4-pin yellow plug that simply plugs into a spot on the OEM vehicle fuse bus panel that is hot when the key is in RUN. That's it. All the rocker switch does is energize the Charge Solenoid either from the House battery (MOM), or from a RUN hot circuit in the vehicle fuse panel. Steve

RE: Need help replacing charging circuit solenoid.

You need a way for the solenoid to stay powered when the key is turned to Start or it will cut off the house battery supply to the starter so you can't start. The MOM switch does not rely on the ignition switch at all. Only DUAL does.
maillemaker 01/21/20 06:20pm Tech Issues
RE: Need help replacing charging circuit solenoid.

Going from Run to Start cuts off non-essentials and the power to the solenoid normally. So there are switches of some sort responding to the key position. You try to start normally but the engine battery is too low. You push MOM and try again using the key to Start. Non-essentials are still switched off same as usual, but this time power stays on to the solenoid (or there would be no power to the starter). Yes. The MOM switch uses the house batteries to energize the charge solenoid. If the house battery power is just passed through to the engine side via solenoid, the brain that gets the power to run and switch off the non-essentials would not know the difference which battery bank is supplying the power. Seems to be the case. Yes. That "brain" is the ignition switch. But now for some reason the brain running the power to the solenoid can tell the difference? I don't know how it works, but the when the ignition switch is in START, accessories are turned off. This is going to be true in pretty much any car. Maybe the MOM by-passes the solenoid to parallel the house with the engine batt some other way, and it all acts the same as when on engine battery, but the solenoid being open in Start does not cut off the house battery power, because it by-passes the solenoid when in MOM?? I don't understand what you are saying here. I think it is really very simple. MOM is just like taking a pair of jumper cables and hooking up a second battery to your engine battery. That's all it does. The difference is instead of jumper cables it's a solenoid operated from the house battery juice. DUAL does the same thing, but it uses the RUN switch juice.

RE: Need help replacing charging circuit solenoid.

Somehow I got the notion that when you turn the key to Start, that cuts off the blower motor etc including the power to the solenoid from the engine battery. That is correct. When you turn the key to start, usually all RUN accessories turn off. If the charge solenoid is powered by this (mine is), then it won't be on when switch is set to DUAL and the key is set to START. With MOM you get house battery power to the solenoid, not any engine battery power if I got that right. That is how I understand it, yes. So with MOM when you turn the key to Start it can cut off Engine battery power to the blower and solenoid, but that power is now from the House, so it all stays on is what I assumed. No. With MOM all you are doing is ganging the house batteries to the engine batteries. The charging solenoid is being powered by the house batteries. But everything else normally run by the chassis system (blowers, radio, etc.) are controlled by the ignition key being in RUN. So they will be off in START even though the house batteries are ganged to the engine battery. You are saying that with MOM, the key in Start still cuts the house power to the blower, but leaves the power to the solenoid on so it stays closed. Yes. So even when on engine battery, all normal, turning the key to Start cuts power to the blower as one event and separately somehow on a different line somehow also cuts the power to the solenoid. Generally, all non-essential accessories are turned off when the key is set to START. This includes the charge solenoid. But when you are holding MOM, it "overrides" the ignition switch power and instead uses power from the house batteries to energize the charge solenoid. MOM is able to distinguish between these two events and only cuts the power to the blower and not to the solenoid? MOM doesn't cut the power to accessories - your vehicle's electrical system does (ignition key). All MOM does is gang your house battery and engine battery together. What electrical things are cut off when the key is in START is up to your vehicle. You can think of MOM as simply a set of jumper cables from your house battery to your engine battery.

RE: Need help replacing charging circuit solenoid.

When non-essentials are cut off with Start, how does the solenoid power stay on when in MOM, but not otherwise? The ignition switch only energizes the solenoid when the switch is in DUAL position. When the rocker switch is held in MOM the ignition switch is not involved at all. The house batteries are used to energize the solenoid. This is my understanding, anyway. The rationale is this: When holding MOM, you are jump-starting the presumably dead engine battery using the house batteries. So clearly you need to energize the solenoid from the house batteries. And you only want them ganged as long as it takes to finish the jump-start, hence the momentary nature of the switch. In Dual, the goal is to charge the house batteries, but not run down the engine battery if the engine shuts off. Thus the ganging is only going to happen if 1) the switch is set to DUAL and 2) the key is in RUN. This way if you arrive at camp and have had the switch in DUAL to charge your house batteries and you shut off the engine you won't accidentally leave the house ganged to the engine and thus possibly deplete both sets of batteries while you are camping, and then find yourself stranded.

RE: Need help replacing charging circuit solenoid.

No, that too, but I meant the loads on the engine battery that are on in "ON", but get cut off when you go to "START" so they are not on at the same time the starter is on. So here is how it works: DUAL 1) Flip rocker to DUAL position. 2) Set ignition key to RUN position (engine is generally running at this point). Engine electrical system now energizes charge solenoid and house and engine batteries are ganged together. MOM 1) Hold rocker to MOM position. House batteries energizes charge solenoid. House and Chassis batteries are ganged together. 2) Turn Key to START. All non-essential loads are turned off in START mode. Engine starts. 3) Release key. It returns to RUN mode. All normal chassis electrical functions resume. 4) Release MOM rocker. Charge solenoid is disengaged.

RE: Need help replacing charging circuit solenoid.

So with the rocker, you can push MOM and now the solenoid closes, then you turn the key to "Start" and instead of the solenoid opening as when powered from the engine battery, it stays closed from being powered by the house battery? So you should turn off the heater fan etc yourself to reduce the total drain on the house when starting? As I understand it, when pushing and holding the spring-loaded MOM side of the rocker, it manually (from you pushing and holding the button) energizes the solenoid from the house batteries. It does not care what the key position is. As long as you hold MOM down, the house and engine batteries will be ganged together. Normally you turn the key to start the engine at this time, and when the engine is running, you release the MOM button, whereupon the rocker returns to the center "off" position, and the charging solenoid disengages. Yes if your house batteries are low then you might want to turn off house energy users to maximize what the house batteries can do. Steve

RE: Need help replacing charging circuit solenoid.

I don't know. I have already ordered a replacement solenoid. It is suspect to me already because when the engine battery was down to 11.6V, and I pressed MOM to gang in the house batteries, the voltage did not change, or change much. I've got to do some diagnosing on the charging system. But for now it seems fine. Steve

RE: Ford Starting /House Charging Question UPDATE Test

If my house batteries are very low and will not turn my generator over, can I engage the "engine emergency start" button to start the generator?Not trying hijack the thread, but it seems to be related. I think so. But I can't do it on my rig because my arms aren't long enough. :) My 3-way rocker switch with MOM (emergency start) is on the dash by the driver. The generator start switch is either on the generator or back on the stove vent hood. My generator starts from the engine battery. I would have to get a helper to hold the MOM switch in order to start the generator from the engine battery. A better solution would be to use the house batteries to start the engine, and then start the generator using the current provided by the alternator (and let the alternator charge up the engine battery).

RE: Ford Starting /House Charging Question UPDATE Test

How can the key be in run and the engine not started? If the engine were running and died by some other means than using the key to turn it off, (out of gas, pop clutch, etc.) then the engine could be off but the key in RUN. In normal operation, however, the engine will be running when the key is in the RUN position. But there is also a START key position and this is different from RUN. Many times things are disconnected in START that are connected when in RUN. This is so the engine starter motor gets all the current. You might notice your radio turning off when starting, for example.

RE: Ford Starting /House Charging Question UPDATE Test

Here is what I think: On my RV (1990 Winnebago Warrior, Ford E350 chassis), the Charging Solenoid, which gangs the house and chassis batteries together, is activated 1 of 2 ways: FIRST WAY: Momentary Position of rocker switch: This uses power from the HOUSE BATTERIES to energize the solenoid. This is a "jump start position", and is to be used when the engine battery is dead. Thus logically you would want to use the house batteries, and not the engine battery, to energize the solenoid. SECOND WAY: DUAL position of rocker switch: This uses the engine battery (or alternator if engine is running) to energize the Charging Solenoid. But, it is hooked up to the RUN position of the key. When you START the engine, typically all other accessories are OFF. I can see this when I start my engine as all of my aftermarket gauges turn on when I switch to RUN, but turn OFF when I keep turning to START, and turn back on again when I let go of the key and it goes back to RUN. My guess is that the Charging Solenoid is only energized when: * Rocker Switch is in DUAL mode. * Key is in RUN position.

RE: Need help replacing charging circuit solenoid.

So with no house charging from alternator, the engine battery showed low voltage as though no alternator, but new alternator same thing. You might have had a big house draw that should have been taken by the house batts that was taken by the engine batt, lowering the voltage. It's possible, but the only things running in the back should have been the refrigerator, water pump in standby, TV in standby, and the Propane/CO detector. And I'm not even sure I had the batteries ganged at that point anyway. Steve

RE: Need help replacing charging circuit solenoid.

How much time between starting the rig and the voltage going up? It could be the chassis battery had to come up a little before circuit board allowed relay to energize. Try to locate the battery control circuit board and post number. You may be OK! I replaced the alternator, and then started the engine. Volts showed about 11.6V as I recall on my cigarette-lighter voltmeter. I got out of the cab, whacked the solenoid, and came back, and it was showing 14V.
maillemaker 01/18/20 08:40am Tech Issues
RE: Need help replacing charging circuit solenoid.

But still want to know about why the loss of voltage as was asked about earlier. Loss of charging was what precipitated my replacing the alternator. After replacing the alternator, I still had low voltage as indicated by a voltmeter plugged into the cigarette lighter (and a status indicator wired to the chassis batter). When I whacked the house battery charging solenoid, and then got back in the vehicle, the volts were back up to 14.0 volts. So I assumed that the Charging Solenoid had something to do with the chassis charging circuit. Now I see it does not. So I don't know what caused the drop-out.

RE: Need help replacing charging circuit solenoid.

Yes, I have an owner's manual, thanks. A digital one is always nice to have also. I think I have a basic understanding of how the charging/isolation circuit works now. I agree this should have nothing to do with chassis system voltage so my whacking on the solenoid was just luck. I'll have to do some more investigating. Steve
