YES, Please give me his contact info. I haven't found someone around here.

I meant circa late '70s - I think I bought it at Sears in around 1976. It's definitely analog.

Ignition ON or OFF?

Right, but other posters have said it could be reverse polarized and that would prevent it from charging my system. Not true?

I'll have to look when I get home.

Right, I didn't mean that I had used a deep cycle battery, only that because I have to charge in between uses it gets run down deeper than a normal battery is designed for (which can be hard on the plates. The battery does hold a charge though.

I've owned the tractor for ~30 years and have never replaced it, but I can't swear it's original. I'll look at the screws when I get home.

If I can find a local guy... So I shouldn't make the screw adjustment you mentioned in your earlier post?
