Hi Len - that IS funny. Congrats on the C-Car purchase. A classic.
I don't want to chase you away, but for help with your contactor setup, have you checked in with the Yahoo C-Car group yet? Someone was describing a similar problem recently (the reverse problem, anyway) :
Fairly active group, and there are some schematics and other good info available in the "files" area.
I'd try there first for getting help - that's where the expertise hangs out. I'd be really interested in hearing your car's story though. I hope you'll post more here.
