We bought our MH in the fall of '02, and never had trouble with the generator, same as yours. Last fall I was doing some service work in the generator and discovered that the nut on the solenoid stud where the battery cable hooks, was cross threaded and never tighten. I remover the battery cable and had to remove the solenoid to fix the damaged threads. If I remember right they are 5/16 NF. Then put everything back to gather. That really surprised because there had never been any trouble, the generator always started. The lug on the cable was twisted a little and there was enough tension that it always worked.

Weather was great this weekend, high 50's. Checked battery connections all are tight and clean.

Rotated flywheel.

Charged battery, it was low, but now fully charged.

Gas tank full, can hear fuel pump pumping.

Tried with chassis motor running at both the remote switch and the generator switch.

My volt meter wires corroded, so can't test solenoid. Will try what Cool Mike suggested, with the lights and also get a new volt meter.

Tried jumping the solenoid, hardly got a spark.

How do I check the solenoid switch?
