I was at TSC needing a six volt battery. The parts guy said it was a great idea to use an 8 volt. No conversion required. I remember them from when I was a kid. Well, I burned out two coils and then put in a 585 CCA six volt and it cranks very slow. I have to jump it with 8 volts. Did I burn up my starter? My 3 year old 6 volt battery was 500 CCA and it was fine until a week ago.

A lesson from my 46' Willys CJ2A...when you put an 8 Volt in it can definitely provide superior performance but you need to take your starter out and have a shop replace the brushes etc. (cheap!) to handle the 8 volts...otherwise, you will burn out the starter and the coils. With a modified starter, the drain on the battery is minimal and does not stress the generator. Without a modified starter, the battery drain is intense and the generator can barely recover...with less and less recovery each time! Also remember never to leave your key in the vertical "active" position for more than a few seconds when the engine is not running or it too will fry out your coil and your points

When I bought my 8n it had an 8v battery in it, and the 6v generator wouldn't charge it well... just enough to keep it running... almost couldn't charge it to get it to start. I added a 6v battery to it, and now all is fine, and charges good.

jj , Im thinking you have a bad ballast resistor, located on the back side of the dash ( kind of a small coil looking thing ) if it is bad or bypassed it will burn out coils on a regular basses,your starter could also need rebuilt if it has bad brushes or a short ( not likley ) Hitting these old starters with 8 or 12 volts wont hurt as long as its done in short bursts . Iv had an 8 volt battery in my 8N for over 2 years with no problem. (I will go back to hd 6 volts when the time comes )

Fast Ed, You are correct! if the Ballast is in the circuit it will protect the COIL even when 8.0 Volts is applied.

Keep 6 volts 6 volts always or you'll fry somethin' (like a coil). Your 6 volt will sound like it turns over slowly - it's SUPPOSED to.

Doubt you burned up starter, but if you have to add extra "juice" to get engine to turn over (rotate), sounds like your starter needs rebuilding.
