RE: How many propane accessories can run at once?

I have noticed that if my refer, HWH, and stove is on propane and the furnace kicks in the stove flame gets very lazy and yellow. I have a gauge that tells me that my propane pressure is good.

RE: On-demand water pump?

In two of your posts you describe air coming out first before low flow of water this leads me to believe the pump is sucking air into the top part where the rubber diaphragm is. If you look real close where the parting plane is and see some corrosion you probably have a leak there. I am assuming it is a Sure Flow pump? If so you can remove the bolts and clean the diaphragm it is probably black anyways and may be torn(if torn you can replace it)and reseal with silicone adhesive along the parting plane.

RE: RV Window blinds / coverings maintenance - replacement, etc

When mine broke I tied the broken ends together with a square knot. There is a lot of excess string. What I learned is you can't have these too tight. I think I wound mine around the knob too many times to keep it from vibrating down, which caused the line to break. Also sometimes the grommet that the string slides on could come out of the hole causing the line to wear and break.

RE: fridge exhaust fans added

31.21 cfm is what it looks like to me. 3121 cfm is comparable to cooling fans on cars at full speed... Your eyes are better than mine. I was guessing 312.1 only because it looks bigger than the average computer fan.

RE: 454 Running Hot

I used .030 fiber glass(cured sheets) but you can use just about anything Aluminum, thermoplastic sheets, or hard rubber.

RE: Paint

From a practical stand point I would choose a white gel coated upper and a earth tone lower(from baggage doors down). Like others have said those swirls and stripes look dated after a while and I think the darker full body paint absorbs a lot more heat than the white. If you used a gel coat upper only a clear coat would need to be sprayed with little masking. Also pigment could be added to the lower section gel coat which would eliminate labor there also. I liked the two tone cars from the 50's but then again I'm old.

RE: 454 Running Hot

The OEM fan clutch moves a lot of air at any speed. It is controlled by air temperature not engine temperature. If you are going 60 mpg on a flat with little load it should not come on, once you hit a hill for any length of time your speeds will drop your temps will rise and it should then come on. When the coil spring sees about 160 degrees it will lock up, when the temps drop it will free wheel. You might be thinking about the electric fan on the front of the radiator. That does not seem to make too much difference at 60 + mph but does lower the engine temps at idle and lower speeds. Some of the older fan clutches have several notches that can adjust what temperature they come on. Mine is a 1996 and only has one notch. You can also clean the spring with a tooth brush and carb cleaner to remove dirt and any grease build up which will insulate the spring and cause it to come on at a higher temperature. Thanks for the info. I don't think mine is coming on at higher speeds. Nor does it seem totally dependent on temperature. For example, when I left the campsite on Monday it was roaring when I left the spot, but I had just started it up. Anything just above idle I don't hear it at all. Like I said, the only time I heard it above idle was when it was really hot after that hill climb by my house. Which again begs the question - am I over reacting to the stock temp gauge? Maybe the fan is working like it should and it really isn't that hot?Jimmy, the fan clutch is suppose to come on when the eng is first started after a minute or so it will disengage and quiet down. If your cooling system is working properly the fan clutch should not come on unless you are climbing a long steep hill or shorter hills on a very hot day. You can check the fan a number of ways. The easiest way is to spin it if it rotates more than several revolutions, if you see silicone leaking out, or if it has excessive play then I would think about replacing it. The fact that it comes on when you start the eng, it comes on after a hot hill climb and your temps recover quickly sounds like it is working the way it should. Like I said in my first post anyone can change parts based on age (we have all done it) but it takes a little more thought to figure out what is wrong first if anything. Do the thermostat and radiator testing first before you start throwing parts at it, it will be cheaper for you in the long run. I would suspect a 30 year old radiator and test that first.

RE: Water leak

Mine has an 2 access panels in the bedroom. The lower one allows you to look under the shower pan at the drain connection. The higher one allows you to look at the shower plumbing.

RE: Wind generators not common?

Well, one thing's for certain... With a wind powered generator, you can lay in bed, with a pillow stuffed over your head and know for a fact whether the wind is blowing or not. We vets may have dreams about Hueys and Cobras. The wind pushes harder than my wallet pushes back to build a tower strong enough to keep from toppling. The Cobras and Heuy's were loud because they were 2 blades. I can tell you the Blackhawks were quieter because they were 4 blades and Comanche helicopter was even quieter with it 6 blades. When I hear a Cobra or Heuy I think of Country Joe and the Fish.

RE: Diesel engine power

The torque/HP question arises periodically. My question is: do all of these engines produce rated torque at the typical 1,600 RPM? What is the difference in the torque/RPM curves? Torque and rpm values vary greatly even among the same engines. My ISB 260 produces 550 ftlbs torque at 1900rpm while another version of that same engine is available with 260HP, 660Ftlbs at 1600rpm. ISB Engine ratings I notice in the ISB chart posted that the ISB 225 has 225hp and 605 ft lbs @ 1600 rpm and the ISB 225 has 225 hp and 520 ft lbs @ 1600 rpm. How can these engs have the same HP and different torque values at the same rpm? Is this a typo or am I not understanding something more basic.

RE: HWH Hydraulic Jacks

Thanks for all the help. It turned out to be ground fault in another area. Works fine now. Glad you got it working. It would be good if you can post where the bad ground was so that others with this problem could check there also.

RE: fridge exhaust fans added

Nice post. On the fan at the bottom it looks like 3121 CFM I can't read a decimal is that 312 of 3,121 CFM? What is the CFM of the other 2 fans on top?

RE: Magnetek Series 6300A Model 6345 Bad?

Old Magnatek converter are sometimes referred to as battery eaters because they put out a constant 13.6 volts which requires owner to replenish battery water on a frequent basis. Many replace them with Progressive Dynamic converters which automatically adjust the charge rate which equates to faster charging and less concern about monitoring water depletion. I replaced my 6300 series with a PD9245 - easy DIY - not expensive. I have a Magnetec 950 converter charger which starts at 13.6 volts then drops to 13.2 when battery is charged. I have heard many times on here that it is a battery eater also but I don't know how 13.2 v or less eats batteries? I also have a 40 amp Vector charger that I sometimes use when dry camping for a faster charge on the genset. When home and battery is charged then I use the battery disconnect if I am not going to use it for a while. I add water twice a year.

RE: 454 Running Hot

Jimmy it is easy to just replace parts replace parts based on age. However I would start with the thermostat and see if it fully opens in boiling water. I think an 84 was a lower thermostat setting (180 degrees). They also sell HD thermostast with a small poppet hole to increase flow. The fact that your system recovers quickly is a good sign. I would buy a HF IR gun and check your thermostat housing and compare it to the temp sensor(sending unit) in the LH head. This will be your temp gauge reading. I found a 20 degree difference on mine. Gauge reading was 20 degrees higher than thermostat housing. Does the MH overheat at idle on a 85 degree day? The next thing I would do is once the engine comes up to temp is to shoot the inlet to the radiator that should be your highest reading then work your way across in a grid pattern to the outlet if you see any cold temp readings this would indicated a plug radiator, look closely where the fan clutch is in the center. If you get uniform decreasing temp readings with no cold spots and a 50 degree drop in temp from inlet to outlet I would conclude your radiator is good. If you haven't already back flushed the radiator with a garden hose at the outlet with the thermostat removed I would do that also. You will have to re-position the fan clutch to take these readings. If your thermostat is the correct one and is opening up all the way, and the radiator is good then I would install an air dam to force air through the radiator and prevent the air from going under or around the radiator. I used thin FG sheets to build mine. Headers and a free flow muffler will also reduce a lot of eng heat. Hope this helps let us know what you find.

What brand of jacks do you have? What series or model? Do you have power to your control board?

RE: Generac Generator

Just because your batteries are reading 12+ volts does not mean the amps are getting to your starter to turn the engine over. It sounds to me like you may have corroded connections at the battery or the generator end because your generator turns over with the eng running. To know for sure I would connect a battery or battery from your tow car directly to the generator. If it starts you have a problem in the cables from your house battery to the genset. If it does not start then I would look at the starter.

RE: Whats the best car to tow ??

The "best tow car" is the one that you want to use as a daily driver. Why have another car just to tow on trips?

RE: HWH Hydraulic Jacks

If you post your model HWH it would be easier for folks to help. The easy things to check if you have the 200 series with the joy stick is the fuse in the control box I think it is a 3 amp glass fuse and the springs when you remove the to cover. There are 3 small springs that need to make contact with the control board.
