Re: '48 Electrical System Polarity

Thanks for the reassurance and good news Howard. Looks like someone did make that change; my ammeter reads as expected and there's plenty of electrical tape on the harness. A little like amatuer hour actually but I'll see about making improvements as I go.

Now, the one type of device I can't get my head around is the relay/solenoid. I'm assuming that a reverse in polarity would have them acting, well, in reverse: pushing instead of pulling, etc. Am I using faulty logic here?

When I'm all done with repairs to the overdrive in this car, I'm gonna post a flow-chart for testing R9 OD systems but here's what I'm thinking: If I ignore the Ground Out circuit at first, I'm down to 3 terminals on the Relay:

1 is Hot
4 goes to 4 on Solenoid
5 goes to Ground

I'm thinking if I get that "machine gunning" from the Solenoid then I'm safe to continue on to the Ground Out circuit, eh?

Thanks,
