Generator accidentally got left uncovered and was soaked over a 12 hour period of steady rain. Dried it out and got the engine running, but lost output. Absolutely no voltage. The capacitors are reading 32.5 and 32.6. Could they be weak or is there another problem? Have not found any wiring damage that could cause a voltage loss.

Start looking at your safety circuits.
1. High water temp
2. Low Oil
3. Low water etc...
From the manual these are the protection circuits.
• Engine protection: low oil pressure, high engine temperature.
• Genset protection: under/over voltage, overload, battery charger failure, battery voltage out of limits,
under/over frequency, start failure.
• Circuit breaker protection: IV poles.
• Differential protection.
Any one of them will trip the fuel relay closed. What you may be able to do is disconnect one at a time each protection circuit and see when the fuel relay opens. (Make sure to reconnect each one if it had no effect on the fuel solenoid)
Once you isolate which circuit it is in then you can chase wires or change the bad switch.

Ground the generated it's self. I had a similar problem after a storm once. First on the generater itself find a flat peice on the frame say by the motor. Sand in down to mettal. Put a self tapper screw in. Now get a 5' to 6' peice of 10 gauge bear copper wire. Attache it to the generator and shove the rest into the ground. Now it's grounded and It took care power surges when I did it. Hopefully this will help you.
