gsxr renegade Posted November 2, 2009 Report Share Posted November 2, 2009 Hi Guys, wonder if someone can help. I've got a k8 gsxr 750 and the main fuse on it keeps blowing. The problem only started last week, the fuse blew and i replaced it. However, it only lasted a week before blowing again, leaving me stranded at my gf's gouse, after having to push the bike for half a mile. It seems to happend randomly, on the way to my gf's house, it blew 4 fuses in 20 mins, but when i came to pick it up, and limp home on it the next day, it got all the way back to my house without blowing. I breifly checked the bike over last night, and all seemed fine, but it blew again on the way in to work this morning Does anyone know what the problem could be? I've never had any electrcal probles with it before last week. I'm not really sure where to start with the fault finding. None of the other fuses have blown, just the main one, so can i assume that the circuits connected to the other fuses are not where the problem is? Thanks in advance!

originalracingsnake Posted November 2, 2009 Report Share Posted November 2, 2009 Sounds like a short to earth somewhere. Check the loom where it is visible, and make sure nothing has rubbed the insulation off it anywhere, if the main fuse is blowing, it must be a big issue causing it, and if intermittant, my money is on a rubbed/overheated/broken wire shorting out on the frame/metal parts.

gsxr renegade Posted November 2, 2009 Author Report Share Posted November 2, 2009 Does anyone know if any of the other fuses have blown if the problem was related to it? i.e. if the fault was in the wire that took power to the headlight, would the headlight fuse have blown as well, or just the main fuse? Or would it be impossible to tell? I'm just trying to narrow down the area in which the fault could be, i don't fancy having to pull the entire loom out to search for it, if i don't have to.

originalracingsnake Posted November 8, 2009 Report Share Posted November 8, 2009 If the main is blowing, it will likely not be one of the spurs, i.e. headlight. More likely to be a short on the starter, earth, main feed to fuse box or anyhwere prior to the accesories. If I were you, I'd be wrapping a gert big nail in tin foil, and hammering it in the main fuse slot. If the bike actually does catch fire, I never said that, right?

Ta Muchly if its a fault in the sub circuits, ie headlights, indicators, fan etc then that fuse should go, most likely if the main fuse goes has to be the starter or its solenoid i would have thought. something is going to ground (shorting) Link to comment Share on other sites More sharing options...

gsxr renegade Posted November 9, 2009 Author Report Share Posted November 9, 2009 Thanks for all the help guys. It turns out that a wire coming from the regulator rectifier had been rubbing on the mounting bracket, and was shorting out. Link to comment Share on other sites More sharing options...
