6 volt negative ground

The coil is marked + and -. Distributor primarily lead is going to + but the battery negative goes to ground. So I believe the coil is still wired for positive ground at the battery. I had to send the generator out as a core before places would send me a rebuilt one so for now I’m stuck. It needed an armiture and fields so it wasn’t worth fixing.. thanks for all the help.
 
It kinda sounds as if the fella that changed the battery just stuck it in mistakenly as neg ground. That takes a little work, but, its done very once in awhile.
 
Make sure you let the people who are rebuilding the generator know that it is a negative ground 6 volt car, unless you intend to change it back to positive ground.
 
Bert’s is doing it. The person I spoke to said it didn’t matter. I thought id make sure it’s polarized for positive ground switch the battery to positive ground then see how it works, use my soon to arrive coil polarity tester and see which way the ammeter goes, lol. Positive ground is so strange to me, never had a car with it before. It’s very interesting to learn more about it and generators.
Thanks all for the help!!
 
Wanted to thank everybody for all the help I received on this thread. I wanted to keep everything as original as possible so I switched it back to positive ground changed the coil and ammeter and replaced the generator, Also tuned it up and set the timing. The engine is running well now. I need to start a thread on the transmission next, lol
Thank you all very much!!
 
Too high of a voltage can also be caused by some bad connections in the charging path. The Model
A achieves voltage "regulation" by brute force from adjusting the third brush for current output against the battery itself. If there is resistance from bad connections, the battery sees less current but higher voltage. Bottom line, check all connections.

The battery doesn't see more voltage, the difference between generator and battery would be "lost" on said bad connections.

But it's easy to check: Put a voltmeter on the battery and compare it to the output-post of the regulator. If the voltage is almost identical your wiring is hood. If there is a significant drop to the battery, you shoud check your wires and connections.
