solenoid acting up
Thank you Gary --- I will do that test. A original replacement solenoid is
$200 and I did not want to throw parts at it -- Michael

Ohms resistance on the coil leads. An infinite reading from the coil leads to
the case and infinite from the main pins to each other, the case and coil wires.
If you get a few hundred KOhms, the solenoid is leaking and will get worse or
eventually catch fire. Also, Activate the solenoid and read ZERO Ohms main pin
to main pin to show there is no pitting or burning on the main contact surfaces
