Hi,
I have Scag Cheetah with a 27HP B&S Commercial Series engine. Starting with a fully charged battery I can mow for about an hour and then, if I stop and try to restart, my battery doesn't have enough power to restart (starter motor just clicks). I apply booster power from a jump start kit and the engine starts ok and I carry on mowing.
After an overnight recharge the battery is at 12.9v. I start the engine and the battery is at 13.9v so I'm getting a charge into the battery while running and the amp meter shows about +3 amps. However, the battery will still discharge while mowing.
Any ideas about what can be happening to the battery charge while mowing? Is 13.9v with the engine running not enough?
TIA - Peter
