This is to inform anybody with a 2003 Honda TRX400EX. I have 3 of them and have encountered blowing fuses. Anybody with this problem this is the remedy. Behind the left headlight plug is the front brakeline bracket if u look the bracket and hose is pushed up against the headlight plug which causes the high beam wire (GREEN) to short out against the headlight frame! Which will cause the fuse to blow which will enable it from starting! Now this problem occurs only at night when u are using the headlight.:eek2:

wouldnt the green wire have to be bare metal like if the rubber came off? Or it can still short out just toughing metal? :confused: Thanks for the info

Yes, the rubber insulation would have to be off the wire and the exposed wire would have to touch bare metal to short. Hmm... :ermm:
