I would like to convert my 37 to 12v negative ground alternator. I see Macs has a 12v neg ground alternator kit. What else would I need?
 
As WGA said: This is one of the most covered topics on this site. You will also find that many replies ask why you want to convert? If you have a problem, there might be an easier and less costly solution. Maybe someone will post an estimate of cost to make this conversion. Might surprise you. John
 
A 6 volt positive ground alternator (single wire) is available. If you have good clean and tight connections throughout, you don't need to convert to 12 volt.
 
Someone once said "a picture is worth a thousand words", if that's so, a video with audio demonstrating the 6 to 12 volt conversion should be priceless.:D Good thing is, they are only $24.95 + $3.50 S&H from Vic's V8 Videos. PM me if you would like a DVD of the 6 to 12 Volt Conversion Video or to find out about our other restoration videos. Vic

With 6V you also need HEAVY 6V battery cables. I made mine out of welding cable 00 I believe. 12V cables are just too small for 6V.
 
I have a rusty generator that is not working and crusty regulator now. It looks like it will cost about $175 to replace them. I can buy the 1 wire 12v alternator kit plus voltage reducer for the gauges for about $220.
I also have two cars with 6v generators which I am fine with. So I agree, no reason to switch at that point. However if I need to replace a lot of parts to fix the 6v then I might as well go 12v and eliminate the obvious downside of 6v such as accessories.
Thats why I'm wondering what else I may need.
Thanks for the advice. Bob

Larry remanufactures alternators and they work great! They also cost less than the high-overhead online parts sellers.

I had one of his 6-volt alternators first, then he converted it to 12 volts. He also has a strong and clean looking slingshot for mounting an alternator on an 8BA.

Larry's a great guy who will take the time to answer all your questions, too.

Highly recommended!
 
I heard that Ed Whitney has a 6 volt pos ground alternator inside a gen housing. i also ran 00 cables and i have lots of power, see if you can stay orig. car is worth more. Ken
