This one has been a real head scratcher in the shop.
The F&R Contactors will not engage on their own.
If we give them a little nudge through the access hole, the snap right on.
This issue has continued despite replacing the entire Contactor assemblies F&R and accelerator.
The EV100 checks out as does the diodes and the osc card.
Voltages are correct throughout and the capacitor checks out good as well using the old Clark "handyman" component tester.
I realize this is an antiquated system but if anyone has some helpful thoughts, we would be grateful!
