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...

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...
