Hi everyone. I am endeavouring to resurrect a 175HD lawn tractor. Not sure what year. It has a Kawasaki FC420V engine. It is charging at 13.3V, which, when using the mower, drains the battery within a few minutes, and the charging system can't keep up. I have replaced the voltage regulator, and the stator, both with apparently tested as good used parts. It is still charging at 13.3, or slightly lower. First of all, should it not be charging at least a volt higher? And if so, what am i missing? Is it possible that the magnet on the flywheel is the culprit? Where should I look next? Thank you!

Welcome to the forum. What is the battery voltage when it's not running? Are you sure the battery is good? It sounds like it is trying to charge. I'd figure normal charging at 13.6-14.2v. You can measure the AC voltage on the 2 outside wires with the regulator unplugged. I think they call for 27-30 vac. That would measure the charge without the regulator or load of the battery. Were the magnets all intact when you replaced the stator? Did it look like anyone had reglued the magnets in the flywheel? If they did and got the polarity wrong it might cause low voltage but most generally the magnets wouldn't be a problem. Another thought would be if the clutch is drawing too many amps.
