Re: Onan Generator Control Problem - RC as solution?

I pretty much threw out the idea of using a RC to control it.

I'm pretty sure the voltage regulator is fried. Right now the generator is outputting 300VAC! This thing is starting to be more of a pain that I thought it would be.

This is what I have found in the troubleshooting guide:

Quote:
"Check Generator" Faults: Fault breaker CB5 trips if generator quadrature winding current is too high.
I talked with an electrical engineer over the phone and he said that it meant that the generator has too much of a load on it. I know this cannot be right since there is no load at all.

It also has this in another troubleshooting area:
Quote:
"Check Generator" Fault -
Corrective Action:
a. Reset "Check Generator" fault breaker CB5.
b. Run with fewer loads, especially when low power factor loads are connected or large motor loads are cycling on and off.
Winding current leads me to think that the actual generator has a shorted winding. I really hope this is not the case and maybe someone has a little more insight on this, as I'm not a generator expert by any means, but am quickly becoming one.

Yesterday, all I did was try to get the water pump working. It took a lot more time than I thought because I could never get the water pump to get a prime. It took 3 hours just to get it primed!

Anyway, 300V is quite high, enough to fry everything in the boat.
