A friends’ Dad was having trouble with his TRX300 Fourtrax and he asked me about it , he told me that when he reved the engine the bike would shut down and not restart and blow the fuse , come to find out , when you put a meter on the battery with the engine running at idle , it would show 15 volts , but when you reved the engine it would go to 20 volts and the fuse blow , so I sold him a rectifier for $20 and that fixed the problem , but boy did I leave money on the table , I had already gave him a price and I went to Partzilla and found that rectifier goes for $195 , well I did my good deed for the week ———– I never seen this one before and thought I’d share it
