We've been having a heck of a time figuring out what's wrong with our generator/voltage regulator, positive ground 6 volt on the '33 Desoto. Sent the generator away back east to be rebuilt. Replaced the voltage regulator (6 volt, + ground), and the amp meter still shows discharging all the way over to the left. Had an electrical shop bench test the two and said they are fine. Any electrical wizards out there? Been considering somehow installing a later model Mopar 6 volt + ground generator and adapting it to make it fit (like what's on our 1940 Dodge). Any experience with this?
Thanks!
I guess we need to start somewhere....
So if the generator and the cut out both test good, but the vehicle's amp meter on the gauge shows discharge, is there a chance that the gauge is wired backwards?
Has the generator been polarized on the car?
Just throwin' it out there.....
It's supposed to be fun!

If you have everything properly installed and the Generator and Voltage Regulator are working, then you have a dead short to ground somewhere in the electrical system. And if it pegs the Ammeter, then it's a major short...
It could also be a bad ground. That was my problem with my 36.
I must have had my generator out of the car and back to the rebuilder at least 5 times. It wasn't until I took the car in that we were able to figure it out....a few slightly loose bolts on battery wire....

Did you ever run down the source of your problem?...
Thanks to all who responded to my posting about the '33 Desoto rebuilt generator and new voltage regulator not charging. Nope, he hasn't found the problem yet. His question now is can he adapt to fit a generator from an early 50's Chevrolet truck (negative ground 6 volt) to work on the Desoto (6 volt positive ground?) He is thinking that maybe when the generator was sent out to be rebuilt, it came back not compatible with the Desoto. Tho the auto electrical shop bench tested the generator and voltage reg and said they work fine. My Dad isn't too computer saavy, so I am the messenger...he's in his 80's and is cursing that he never had problems like this with any of his past Mopar vehicles! If anyone is knowledgable about this, any advice would be appreciated. Sincerely, Margaret
Tim had asked if the generator has been polarized. We never heard anything back on this. Please have the tech do this. The techs do not necessarily know to do this nowadays.
