Hey. I've been blowing headlight fuses left and right. it had a 10a fuse in it so that's what i've been replacing it with.I put probably 3k miles on the bike after i got it before the first one blew, which happened after i let the bike sit for abouttwo months (we had a warm day in PA). would putting a 20a fuse in be a bad idea?

 

Yea your just covering up a problem if you put a 20a, youll fry the wiring then the fuse will blow. Check your power/ground wires to the headlights thats why a fuse blows

 

check for short circuits i.e. wires contacting/deposits on a connector/worn insulation et al.

 

there are'nt any bare/crossing wires that i could find. next i guess i should check the contacts. my guess is it's the connecter from the headlight assembly to the main wiring harness because the rubber boot thing apparently vibrated off and wasn't covering itwhile my bike was parked outside. man this sucks.. why can't i just go out and ride.

 

Open it up and check the green ground wire thats a problem, then dielecrtic grease everything up.

 

Sorry buddy, I know the feeling - definitely don't want to put in a higher amp fuse though like was already said, you would be covering up and creating more of a problem. Use a multimeter to find the bad spot and fix it up, it'll be worth it in the long run to take some extra time now to fix this issue up right. And you CAN go riding now - just keep some extra fuses in your pocket

 

what you want to do is maybe replace your fuse and take apart your bike a little to expose your wiring harness. Then try to wiggle and play with your harness and see if there is a certain location, or connector that when you play with seems to blow the fuse. Then that will help narrow down your problem. Also your blown fuses....describe them. The area where it is blown..is there a black burnt area, white blistering , or does it look like nothing is burnt at all If there is nothing that is burnt at all, then it might be a slow burn which means you have a lower resistance problem and causing enough current to pop the fuse but not immediately! Which is going to be a pain to figure out. If it is a fast pop then you are lucky, you'll be able to find the frayed, or broken wire that is touching ground and causing this.

 

surfinScal:

very good insight... it is a slow burn. however, it leads me more to believe that it is a bad contact in the headlight assembly connector like i suspected. i'll find out tonight!

 

Maybe you should first check what kind of bulb you have in there. If you bought the bike used, maybe the previous owner substituted the headlight with one of higher Wattage (ie a brighter light). That would cause your fuse to blow (as well as possibly melt the fixture)
