HELP--- generator wont stay running

[Ryan Wright]

Ed,

When you hold the solenoid open manually, does the generator provide
power to the coach?

If not, your problem is either the voltage regulator or the brushes.
Check the brushes first! I had the exact same problem as you with no
power to the coach, & I made the mistake of just buying a new voltage
regulator because it seemed easier to replace, $180 and it turned out
it was the brushes, $20, and they were actually easier to replace once
I found them. Now I have a spare voltage regulator I didn't really
need.

If you DO have power to the coach when you force the generator to run,
then your problem is likely the coolant temperature switch or the oil
pressure switch.

I'd put my money on your brushes...
