This thread troubleshoots the half reading issue; https://www.steelsoldiers.com/threads/mep-802a-m8-percent-load-gauge-issue.212356/

Here's what you should do to test your generator.

You'd think with all the over done stuff on these units, the'd have had put something on those unused mounting holes as guides or holders for that cable.....

I soak with Super Clean first, then spray with a hose. Do it a few times. No need to use a pressure washer as the Super Clean breaks up most anything grimy. If needed, get a brush or something. With just a hose, usually you don't need to worry about electrical, but it's a rule of thumb to never...

It's the same fitting, just the brass draincock threads directly in on the MEP 803A vs a NPT to AN-4 that goes to the hose. Why they just didn't make it the same, coming out the side of the frame..... military! Same as the top fitting on the tank as well.

You got it from me it seems. I know the issue you're talking about & mention it in the item description as I have run into it myself on the installations. I recently ordered a whole bunch of things from various distributors to try and solve the issue of tanks and the holes not linking up well...

I check for 12v on the body harness side. Confirmed wiring is good all along it. Also from the switch to the TCM connector itself. I used a multimeter to adjust it and make sure it opens/closes with a slight pedal touch right at the TCM connector (Not J1, at the actual purple connector) so I...

Well, it is plugged in, brand new, tested good, and everything I can tell so far the wires are good. Two TCMs that are new tried as well. So it more than likely is not the sensor itself, but something messing up the signal coming from it. There is no light with the J1 disconnected and power so...

Tested the wires today. From J1 to h for the Engine Speed Sensor tested good, p didn't give me continuity but looking at the wire diagram, it is shared with the Throttle Position Sensor and then grounds in the transmission itself ultimately..... I think? When you have a bunch of shared...

This may be helpful. The injection pumps can be annoying to remove/install but on an MEP 803A there is MUCH more room! I'm betting that someone already messed with them & installed them improperly. Have seen it quite a few times. Hopefully that rail isn't bent! Usually you can make it move no...

I think I need a few parts from a MEP 501A control box. If you are interested in selling, let me know.

While you have it apart, soak in ATF for 24 hours or so. :)

Injection pump replaced & truck is running. The new Crank Position Sensor didn't do the trick. Will double check the wires between TCM and the sensor. Thinking it's just the TCM at this point. If the wires above test okay, going to install another new one & hope for the best!

I know nothing about this specific setup, but one think I learned about military communications setups.... just because it is the same connector, does not mean it is the same pin out. Unless you can 100% confirm it is the EXACT pin out.... just because it fits, doesn't mean it won't turn...

Funny, once you know, how the stuff starts popping out. Maybe it was for putting the Jerry can handles through? :p
