You CAN keep the old 6v coil and add a resistor.. OR you can get a new coil. napa IC14SB is about a 15$ coil, and needs no resistor. It's what I use on all my 12v gassers.

As for the 1 wire alt. I find them less desireable.

see if you can make it run 3 wire. IE. jump charge stud to #2 spade, then with it running at 400 rpm, hit #1 spade with power and see if the alt turns on. if it does, get a 194 lamp and run a line from the coil side of the key thru the lamp to the #1 and have a 3 wire alt...

I've always just used a resister for a late 50s Chevy you can get them from NAPA for about $10 and use the same coil. Just swap the small leads so the polarity is right.

The coil needs to be changed to a 12 volt, 3 ohm internal resistor coil. There is a great article right here on this site in the research and info area called Ford 2000 & 4000 12 volt conversion that I have used to convert two tractors so far with no problems. I did not use any kit, I rounded up the items seperately. The beauty of the one wire marine grade alternator is that you do not have to rev the engine up to excite the alternator.
