autumnwalker Posted October 19, 2020 Report Share Posted October 19, 2020 So my "new" tractor isn't charging the battery. It will start fine when the battery is charged (tender). When the tractor is running (full throttle) the battery shows 12.5V. Tested the battery and it's showing 286 / 300 CCA. This leads me to charging system issue. Anyone familiar with these? It's a JD branded Briggs & Stratton 20HP motor. I've been trying to research. I believe this is the model 40N877-0002-G1. Thoughts? Link to comment Share on other sites More sharing options...
autumnwalker Posted October 19, 2020 Author Report Share Posted October 19, 2020 Does anyone make a "Haynes Manual" for these? I found a parts diagram. Looks like there is an alternator, a magneto, and a regulator. Link to comment Share on other sites More sharing options...
SQRLPWR Posted October 19, 2020 Report Share Posted October 19, 2020 Probably the regulator...my 'guess' I replaced mine way back, but it was the Kawasaki engine. Link to comment Share on other sites More sharing options...
