Mark,
It certainly could be the solenoid, but any of the switches in the
circuit or the wiring itself could also cause the OD to work
intermittently. The best way to eliminate the other things is to ensure
the ground side of the Solenoid is securely attached to a solid ground
and apply 12V. to the other terminal and see if it engages. If it does,
you then need to troubleshoot the rest of the circuit (switches and
wiring) to ensure that there is continuity throughout. Sometimes the
switch contacts get an oxidation on them if they have been idle for a
while.
Regards,
Joe Curry
