Briggs 400707 won't charge battery
Hi there. I just discovered this forum and hope I can get help with a 4-years-old problem!!!
I bought a used 1988 Columbia lawn tractor 4 years ago, equipped with a Briggs&Stratton 14hp engine model 400707. Maybe 1 year after I got it, it stopped charging the battery while running. I replaced the battery with a new one, but it lasted for a few starts and died. If battery is fully charged, it could starts. But if I miss the start, battery will just go out of energy after a few starting attempts. Engine is starting and running fine if I boost it with my car... but if I stop the engine, it won't restart.
At magneto's connector near the engine, I measure 13.8V with engine running. As I remember from last summer, I measured 12.8V at battery (should be 13.8V, no?). Does anyone have any idea? I guess the electrical schematic would help alot...
