Blowing the 30amp fuse

Post by ofloinn3 »

My beloved '94 failed me again. The 30 amp main fuse blew. I replaced it and rode it 74 blocks, it sat for an hour. Rode it for 45 more block to the gas station with everything good. Pulled out of the station and got 4 block down the street and it blew again. WTF!! My guess is I have something grounding out. I dont know where to begin to look. I guess I need to pull the tank to access the wiring.

My bike is 150 miles away right now. I rode it to Delmarva Bike Week from Baltimore on Friday. I have someone trailering it home for me on Tuesday. I was afraid to ride it across the Chesapeak Bay Bridge and have that fuse blow. I would be SCREWED! Plus I would never know when it would just blow. I dont need to be getting ran over when it dies on me.

Anyone delt with this problem? banghead

Sounds as if you have a dead short somewhere.

First I would get the bike back and then I would do some testing....ride it around the neighborhood.....stop and pull the seat. That fuse HOT? If not ALWAYS hot (getting hotter and hotter til it blows) you KNOW you have a vibration/pinching wire type intermittant fault.

Big suspects for that are the big bundle that goes from the main chassis harness through the frame by the headstock....check for chafing there, and the right hand handle bar switch housing ('start' and run/stop button).


If that fuse is hot after just a few minutes...it's pretty much a permanent issue and may be 'tripped' by using the brake light/signals, etc. Check the wiring near the battery and start solenoid.

Allright!!! I found and fixed the problem. A wire in the main harness had rubbed on the end of the radiador exposing the copper. Looks like it runs back to the fused box and onto the relay. Which was heating up and causing the fuse to blow. It acually took me longer to find time to mess with the bike than to find the problem. I took the tank off and didn't even need to. Oh well, problem it fixed. I'm back in the saddle again ... :yutugh2:

Reelrazor ...thanks for your response an this one. :cheers:
