It has all the info on the operation of the heater.
Essentially it burns diesel fuel and circulates warmed coolant thru the engine block.
I use a pair of the 12 V Deltran Battery Tender Jr's on my 802A. $26 on Amazon. Just wired each charger/maintainer to each of the batteries. Not need to disconnect the batteries from each other or from the genny. The charger outputs are "floating" so no issues with connecting the positive of...
Does the fuel pump run with S1 in the Run position?
Is the S17 Emergency Stop switch pulled out?
Is the Battle Short Switch in the down position?
The 24 volt power path from the battery to S2 is...

Resistive loads are a 1.0 power factor. With a 1.0 PF load the 802 can provide 5000/0.8=6,250 Watts
If you are running a purely resistive load such as a water heater and incandescent lights it should happily put out 6,250 watts and would be at 100 % load on the meter.
I verified this yesterday...
My parts manual TM 9-6115-642-24P indicates its a 88-20003
Here's a replacement: http://www.southernautomotive.com/catalog/product_info.php/products_id/1006
The A3816 appears to be a basic Well Nut.

You might be able to unscrew the old valve from old well nut. If it no too deformed you may be able to insert it back into the tank and then screw the valve back it expanding the well nut...
The voltage adjust "Switch" (potentiometer) is part number RV4NAYSD502A. It's a 5K ohm 10% 2 watt potentiometer.
You can order them from:

In looking at the fuse mod in my genset it appears to be done exactly per TB 11-6115-741-24 chapter 5.2.
According to the TB all MEP-802,812,803 & 813's get the fuse mod during the Tier 1 & 2 resets which explains why newer gensets would not have have the fuse mod yet.
Adding the MOV across the...
It's a 1994 and came with the quad winding fuse mod already installed in it.
I respecfully have to disagree. MOV's conduct in the presence of both voltage transients and steady state voltages.
I believe you may have misunderstood where the MOV would be in the circuit. By having the MOV...
I did some peak voltage readings with a digital scope on the quad circuit of my 802A (regulator pins 7 & 8 )during cranking and running.
The worst case peak AC voltage was ~90 VAC just as it started to run and the quad voltage settled to ~70 VAC while running.
I plan on installing the MOV...
Regarding the Fuse Mod...
Here is a link to TB 11-6115-741-24 that has the original info on the Fuse Mod, Generator Tier Resets etc.

A bit more information after looking into this. The fuse mod is done to protect the generator head...
My 802 had the petcock drain ripped off the radiator. Nothing left but a hole the size of a dime in the brass side tank.
I closed up the hole by soldering a clean penny over the hole.
I just wire brushed the brass so it was bright as well as the penny.
Used a big Weller soldering gun to tin the...
Thank you all for looking at your gen sets.
After digging thru TM9-6115-641-24P I found that they used two different Ground Fault Interruptors when they built the 802's.
Page 32 Figure 8 shows the GFI item 11 in detail B with a fuse holder. The following page listing the parts indicates that...
