Kohler 12.5 Yanmar Engine Generator Not Running ?

[fmc360]

Engine will start but will not keep running. start solenoid will not
open injection pump. Items not working or not powered:
l. start solenoid 2. Oil Pressure gauge 3. Water temperature
gauge 4. Radiator Blower
Looks to me like the engine is in auto shutdown mode. I need to
know where the circuit breakers or fuses are for the Oil Pressure
gauge, fuel solenoid and blower.
The Coach is a 89 PT 40 I have already replaced the
battery with no difference.

It is not making electricity. If AC (current, not air conditioning)
isn't present, the engine will shut down in a few seconds. You have
an internal problem in the generator head unit.

I agree with Scott. I've had that happen three times (no AC to run
the blower). Once was the voltage regulator and twice it was a
broken brush wire. (Until I realized I needed to replace the
commutator slip rings).
