What did I fix? Jim may be able to explain this miracle.
Healing hands. Ever thought about a career in evangelism? Probably you had a bad connection and mucking about with it disturbed it into working. With luck it's gone for good, but if not you have a really good place to start looking next time. An '82 ought to be capacitor-free, IIRC. Just a relay, a cam, and a bunch of switch contacts in addition to the motor. -- Jim
