So...I had a low battery problem. After a few days of spraying every lawn with the electric pump. I thought my voltage regulator or alternator (stator) was bad. Electric start gradually failed. I did some research and found that many Briggs small motors had a stator that puts out 3 amps. And I looked up the one-gpm Flo-Jet pump that I am using and found that it draws 2.5 amps. Considering the draw by the starter, maybe there just was not enough juice to go around. I put a battery charger on the nearest hot wire and charged up--now starter works fine. Pump, too. We will see next week. Am I on the right track?
