My 1952 8n has suddenly started draining the battery overnight. Here's what I know: It was converted to 12 volt by previous owner, but I've owned the tractor for 22 years with no electrical problems. It has started quickly every time. The battery is 720CCA and slightly more than two years old; the battery works without problems in other tractors and cars. Now, I can fully charge the battery, but it discharges overnight. I'm embarrassed to say the ammeter has never worked, and I've never pursued it because I've never had problems. Now I do. Before I do too much reinventing of the wheel, what advice can you offer in tracking down the problem?( I'm somewhat electrically challenged with anything less than 120/240, and I haven't needed to work on 12-volt stuff for at least 15 years.) I'm thinking stuck or bad contacts in regulator, but does that make sense? I also have to check for a bad wire somewhere. Other ideas? Thanks.
