I have a 1930 model A and have heard that you can use the 6volt generator in a 12 volt system. How is this done? Thanks

Hey davew, WELCOME to the VFF!!
Something tells me I need to get my original Powerhouse generator back and set it up on my 12v and do a topic on it.
Basically dave, the generator can put out up to somewhere around 40volts. The thing that defines how much it will put out is 2 fold. First, the storage device and the cutout setting. If you attach it to a 12v battery, it will charge the battery until it is full, the problem is that without 12v cutout it might run as soon as the engine is stopped and drain away whatever charge was in the battery. So, that being said, a generator will charge and maintain a charge on a 12v battery. You just need too be able to cut off the angry pixies when you stop the engine.You wana look waaay far up da road and plan yer route because the brakes are far more of a suggestion than a command! -
Thanks for the replies. Been thinking of going 12 volt and like the look of the standard generator.. Maybe adding a 12 volt outlet and signal lights but that would be about it. I will look into the fun projects regulator. The model A is a retirement present to myself so just learning. Its been a fun and interesting ride so far.Comment

There is a company selling a 12v alternator that looks like an original long style generator,,, I forget the name at the moment
Just sayin
But the other info above should help you out as well3~ Tudor's & 1~ Coupe

If I do a negative ground system will it be a problem?Comment

You can re-polarize the generator.... read our generator info thread in the chassis tech forum3~ Tudor's & 1~ Coupe

I'll link these two tech threads from the chassis forum for you anyway. Maybe you'll pick up something extra from them

Great information. Thanks, think I'll give this a try.Comment

I’ve read a lot of posts on this, but the procedure still isn’t completely clear to me.
I’ve just disassembled a generator to re-wrap the field coils with Scotch glass electrical tape, and then cleaned and re-assembled it.
It will motor with my 6 volt 10 amp battery charger attached to it - negative to output post and positive to generator case.
If I connect...12-15-2020, 06:07 PM -
I am looking at a 1931 CC Pickup that has been converted to 12 volt. What would be involved in changing it back to stock 6 volt system?08-10-2020, 02:57 PM -
My 20-year-old Peterson voltage regulator has shorted out for the last time. I’m on the waiting list for a new fun projects. In the meantime I was going to just rebuild a generator out of the 30 or so junkers I have laying around and I found one with brand new red field windings in it. But I don’t know if they are 12 or 6 V. The other thing is, I found a horrible generator with a electronic board...You do not have permission to view this gallery.

I just got the coupe back on the road after a long spell in the garage for various repairs. Among other things, I installed a new wiring harness, new headlight sockets, new LED headlight bulbs, and a rebuilt generator with the TomW EVR. I've immediately noticed two problems.
First, the generator is not charging the battery. I'm unable to get the ammeter to move into the "charge"...10-31-2021, 06:29 PM -
Good afternoon - I believe I know the answer to this already after scouring the forum but just need clarification, the three wires running to the Generator Cut-Out hook up to the Battery Side Terminal - Correct? Reason why I'm asking is my generator has a Nu-Rex Positive Ground Cut-Out and all the wires are running to the Generator Side Terminal. Not sure why it would be hooked up this way?

I saw or had this info, but can’t find it.Tom W I think, expressed it. I know the 6v will draw 4.5/5 amps thru the field windings with a 6v battery charger.07-14-2020, 06:54 PM

I'm running a 6 volt generator on a pos. ground system. I was afraid the old cut out was over charging the battery. I replaced the old cut out with a new NUREX semi-conductor cut out. At regular idle the amp meter shows about 5-6 amps of charge. Running down the road- 40mph it shows around 12 amps charge. No lights on. What is the correct charge rate? Maybe the old cut out wasn't bad after...08-17-2017, 11:28 AM -
A friend just called and said as soon as he turns the ignition switch on the generator runs or tries very hard against the belt.The first thing he did was replace the generator and same problem.Going down tomorrow to look.
Ideas on possible causes very welcome.This one has me stumped off the top of my head.07-01-2019, 07:38 PM -
I've read the articles in the electrical reference regarding generator rebuilding. It talks about testing a generator out the car by seeing if it motors. I assume this means runs as a motor for a very brief period. Being electrically challenged there is not enough specific information for me to understand how to do this using the battery eliminator I have. I bought the battery eliminator because...01-03-2021, 03:43 PM

Designed for 20amps. My. Question is can I adjust generator at full amps and this will act as a regulator not to overcharge the battery. If not is somthing available to work.
