Generator Problem

[Ralph L. Fullenwider]

Hi Robert:

The fuel solenoid is what your holding slightly to run the generator. There
are several things that will be the reason for it not to pull in. So here
go a few questions to you;

1. Is there voltage on the coil of the start relay located on top of the
starter?
2. Does the starter actually try to turn the engine over?
3. Check the fuse or circuit breaker on the control box?
4. Check the coolant fluid level?
5. Check the oil level?
6. checked to be sure wire did not come off the high water temp switch? and
grounding some where. or hwt switch failed closed.
7. Wire off the oil pressure switch?
Answering the questions are the first steps to be taken, I write the checks
down as I go to keep track of where I have been

Now then, with the engine running, you say there is no output from the gen
set? and does your Coach have a manual or automatic transfer switch?

Further checks;
1 As Ernie said, check the state of the gen battery
2 check the diode on the curb side down by the oil pressure sender.
3 Check the bearing in the end bell, does it move up and down greatly with
a screw driver used as a pry bar?
4. Is a wire broken off one or both brushes on the slip rings?
5. is the diode and fuse on the quadrature windings ok?

Answer those questions and we can go further

Safe travels,
