DHS Drash 25KW generator relay fault

[Turner81]

Good evening,
I have a DHS Systems drash shelter trailer and I am having a problem. I can normally figure these problems out but this one has me stumped.

The generator leads and breakers are producing voltage under 25volts. I went through all of the steps to test and field flash the generator.

When I put 12+ to the F+ and ground from the same battery to the F-, the K6 relay lights up and shuts the generator down. I can hook the wires up before starting and as soon at it starts K6 relay lights up and the machine shuts down. I have field flashed several generators of this type many times before and never had this problem.

I have now pulled the generator off of the engine and I have tested the diodes. The diodes test out fine.

Any pointers would be appreciated.

usually if it just needs a field flash, then you'll be down in the 2-5VAC range, at least that is my experience with other brands of generators.

I have little experience with the gen you are asking about, but my first places to check on any unit not producing electricity are voltage at all the voltage regulator connections, and checking to see if there are any shorts or opens in the windings of both the rotor and stator, or if anything is shorting to ground.

Got it figured out. Voltage regular wasn’t working and 1 of the oil pressure sensors was faulty.
