I have a 36" Toro walk behind that had a 14hp Kohler that blew up. A repair shop replaced the Kohler with a 14 Kawi FC420V. This motor is constantly burning up the wiring harness. It has burned up three harnesses in about 1 years time. I have also replaced the voltage regulator twice. Does this motor put out too much voltage to be used on a Toro, or have the two seperate shops just used the wrong regulators? Please help as I am at my wits end. Thanks!
