Hi Guys.

I would like to replace the electrics on my Model A. My previous owner had tried that before. Unfortunately, he didn't use proper cables. Too thick and all in the same color.

I want to change that now and also retrofit some things. In the course of this, I would also be interested in the type of generator my previous owner installed. The car is currently running at 6V, positive ground.

To install a radio, however, I need negative ground.
Is it enough to replace the sheet metal on the generator with the cable connection? What else needs to be reversed? Battery is known ...
Ignition coil? Horn? Ammeter? What happens to the starter?

How much power does the generator have?
Then the generator has two plug connections on the side. What are they for or what can they be used for?
The following inscriptions can be seen on the top:
115627
76A
6B13
12VNEG

The problem is, it's definitely a 6V generator !!! The 12VNEG cannot be correct. It is therefore questionable whether the 76A is also correct.

My aim is to be able to determine which cable diameter I need for the line to the ammeter.

Some Pics...

Andy, -actually, that is NOT a generator, ...but was originally a GM Delco Alternator that has likely been converted to 6 volts by changing the internal voltage regulator. You can either replace the regulator, ...or you can convert it back to the correct style generator.

Or, just replace it with a common 12v alternator, and convert everything to 12volts. You may need help accomplishing this if you are not very electrical savy.

Sorry, I meant Alternator.
I have no problem with the alternator itself.
Not even with the 6V. It also works great.
Auto electrics in itself is not a problem if you know what you are dealing with.

So first of all I would only be interested in whether I can think that this alternator really does 76A. Whether it can be easily converted to neg ground and what the side connections are for.
