Troy Bilt mower on 4th battery
Troy bilt super bronco on 4th battery. Took to McStephensonÃ¯Â¿Â½s in Jacksonville Fl two times and was returned both times and they said it was fixed. The belt was also coming off. I fixed the belt problem (they put the wrong size on) and one of the pulley arms was bent down so I bent it back up and the belt stays on great. On the battery issue they said they replaced a solenoid wire, and rectifier. I put a fourth new battery in it after I replaced the stator and voltage regulator and it ran great for 3 cuts. I checked the voltage on it before each cut and it was good. After the 3rd cut I left the key in it in the off position (the other times I took the key out). Went to cut the next time and the battery was dead. Not just drained but sulfated like the other ones. Put it on tester and it has a bad cell. Has to be a parasitic drain. Took the switch off completely suspecting the switch was bad, hooked up multimeter on 20V dc to the disconnected negative cable with other lead on negative post. Reading 12.3 volts dc when it should read zero (used battery from my other mower). With the multimeter still hooked up, disconnected the PTO safety, seat safety, reverse safety switches and headlights Ã¯Â¿Â½one at a time and the drain was still thereÃ¯Â¿Â½still 12.3 volts when it should be zero. With the meter still hooked up took the stator wires off voltage regulator and drain still there. Took the middle wire off and meter went to zero (no drain). I find it hard to believe another voltage regulator is bad. Also did same with solenoid wire and drain still there. Also when I disconnect ampmeter the multimeter goes to zero (no drain). Took elec tape off whole harness from back to front and corrugated tubing and checked for broken/worn wire, wires touching, wire pushed up against something and found nothing. This mower is possessedÃ¯Â¿Â½been messing with it for a year and a half and itÃ¯Â¿Â½s still killing batteries. Before I replace the ignition switch, voltage regulator AGAIN, and possibly the ampmeterÃ¯Â¿Â½.any suggestions other than drive it into a nearby lake? Have spent over $500 in repairsÃ¯Â¿Â½probably could have bought a new mower by now but IÃ¯Â¿Â½ve invested so much I just want to fix it.
