I have a Troy Bilt RZT Mustang ZT 50 with a Kohler Courage 25 engine. After 4 years of use the fuse would blow within 2 seconds of running. I replaced the regulator rectifier and got along fine for about 3 months and then it started doing the same thing. So I put another regulator rectifier on and within 5 mowings it is doing it again. What could be causing the regulator rectifier to be going bad? Any help is appreciated because this thing is driving me crazy.
