My motor kept dying on my last weekend at the lake when I would run at top speed. It didn't chug like it was out of gas it just suddenly lost power. It would start again and run like a top then die again. Back at home on the muffs I noticed the tach is not working. Could it be that there's a short in the main power somewhere and when it shorts it's killing my motor and blowing my rectifier? Thanks for any help guys!
