Peter, Thanks for the insight, but I don't think the relay itself is bad, I think the circuit board is bad. If the relay can be checked without power (because when you remove the cube you have no power to check with) I could put a DVM on it. But that would only tell me if they're stuck closed...

The fried resistor is a 1500 ohm wire wound power resistor. I found a 1470 ohm and replaced it. When I flipped the board over to solder you could see the heat had made its way to the rectifier. The K7 relay looks like it has been in and out a few times. Someone glue it back in with blue RTV. I...

Update- Problem with the dead genset is partially fixed. I removed the DC relay box and found a fried shunt. It is made of brass so with a little solder magic it is back to life. I am still having a problem with getting juice to the fuel pump, injection pump fuel cut off solenoid. I believe...

Thanks Def, I removed the connection box and found a huge fuse/shunt that was blown. I replaced it and I now have power back to the panel. The reason all this happened because I was looking for a cause for no power to the fuel pump, injector pump solenoid, oil pressure gauge not registering...

Keith thank you for your info. Your right I was not in the military. I purchased a couple of these gensets from GL. Most of that stuff is in need of repair, so this is my attempt to remedy the issues. It is apparent that you have extensive knowledge of these gensets. I appreciate your help...

What manual is the -34 manual referred to by speddmon for testing for the cv/cvt. Thank You!

The switch is set to single phase. I get the right voltage out. I have a second genset on the trailer and I have measured voltage at the terminals of the gauge and it reads exactly what the output is.

I was investigating the reason for the dc circuit breaker not working on the front of the genset. I removed the cb without disconnecting the battery (really dumb move) it seems someone had wired all the wires to one terminal. (probably because the breaker is bad) none the less, I touched the...

I'm having issues with the gauges on my MEP 003a. I have full ac power output 110 and 240. It can be adjusted to rise to about 248 volts. The power at the back of the gauge is 22-38 volts the gauge does not register any voltage. The load gauge is also inop. The freq gauge is working and can be...

MEP-003a. Voltage problems I have read these posts looking for a fix for for my MEP-003a. I'm sure my issue has been addressed in this thread, but I'm a slow study and working with voltage is not to be taken without caution. My engine runs great at all rpm's. Ac 110 accessory outlet on front...
