The voltage adjust "Switch" (potentiometer) is part number RV4NAYSD502A. It's a 5K ohm 10% 2 watt potentiometer. You can order them from: Digikey $8.99 http://www.digikey.com/product-detail/en/RV4NAYSD502A/RV4N502C-ND/222807 Newark Electronics...

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. https://www.logsa.army.mil/etmpdf/files/080000/082917.pdf 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...

Haven't found any yet but will keep looking around in and under it to see if there are any.

Ahhhh... Thx!

Found these wrapped up in tape inside the Aux Fuel Hose storage compartment. Any idea what they are?

Got my 802A running today :-) I plugged in a 1,000 watt heater into the outlet and within a couple of seconds the heater stopped. No power at the outlet. According to the schematic CB3 controls the power to the out. I looked all around the control box and no CB3 to be found. What I did find...

I followed a lot of the pointers others gave here about closely looking at the pictures for hints of problems, scavaging, incomplete repairs, exhaust flap etc. I won a unit during the 3/17 auction at Ft Meade. Drove down & picked it up on 3/24. Engine was dry with no water in the cylinders...

Bought my first MEP-802A and picked it up at Ft Meade on 3/24/14. I dealt with both Dan and John there with arranging a pickup date/time and the actual pick up of the genset. Both guys were very pleasant and helpful. :-D Upon arrival I checked in with John, he had the paperwork all ready and...
