PostSubject: In search of the lost short - 20a blown fuse   Tue Nov 08, 2016 9:28 am

Last night I had the GRiSO suddenly quit in the middle of my commute. Since this is the second time I'm getting used to it. The first time I took the GRiSO to the Dealer. It wasn't bad $100 bill with the identification of the blown fuse. I didn't expect them to find what caused it. Next time I'll check the fuses before I make any calls.

So now I carry an ample supply of fuses. With this second blow, I pulled in the clutch, found a good place to get off the road, removed the seat, had to use a key to get out the little fuse --note to self buy a pair of fuse tweezers-- and put in new 20a.

At 46,000 miles on my G11 I figure it's wear in the wiring loom.

Now I figure on pulling the fuel tank --- fun Crying or Very sad -- and searching for that damn short!

If you remove the injectors along with the tank it's actually pretty easy, just undo the single screw that holds the injector cover (and injector), then gently wriggle the injector out of its o-ring, and feed the injectors out thru the bike while lifting the tank off. Another great Pete Roper suggestion.

I did it by myself a few weeks ago (with a full tank) while standing on a ladder (my GRiSO is on a elevated work ramp).

Note: be sure not to lose the injector mounting hole metal insert which can fall out. I took mine out and retained them on the mounting bolt by screwing it into the frame.

Which 30A fuse is blowing ?
There are two, both go to the ignition switch,  one also connects to the alternator, the other also goes direct  to the dashboard. You may cut down your diagnostics time by following the wiring diagram connections from the blown fuse ?

Finally, is the fuse actually blown, and not fractured from vibration instead ?

Good luck, I hate intermittent faults, they're the hardest to find.

Take you earth wire off your starter motor and clean underneath it. Mine blew fuzes repeatedly and I had a few tows and made a mechanic wealthy since he also checked and replaced everything but that.

Pete on here said to check the earth wire, it looked pristine so I never took it off. After many weeks, finally unscrewed it and had green crud under it. Emery paper and a copper washer solved the problem.
