Hello there, Please help me!

I have a 2003 600RR, the fuse in the circuit related to the fuel priming system has blown twice. Once when I accidentally stalled, which resulted in a bit of a lurch forward, and a second time when I was riding along a somewhat bumpy road at a constant speed. The second blown fuse did NOT happen immediately when I hit the bumps, it was a few mins after. Don't know if thats important information or not.

Anyways, I've replaced the same fuse twice, they blew a few weeks or a month apart from eachother. I'm thinking there must be a short in the system somewhere. I don't have much money but I definitely want to keep the bike.

ANY help at all would be extremely helpful with regards to how to approach this issue. I'm not very good on electronics but willing to do whatever it takes.


On another note, the bike has been put away for about a month, and won't start. I've charged it, go to start it and tries to turn over. Try it again a few mins later it gets closer to starting until it starts to sputter but then dies again. Then after that it barely wants to crank. I'm thinking its just the old battery but perhaps you experts may have a better idea.

Please help!

I would start by checking the R&R to see if its working. A lot of "funny" electrical things can happen when they fail high. The simple way is to measure the voltages idle, and higher rpm's. You'll need to get the bike running to do this though. If you can't get it running, you can do a multi-meter check. Plenty of help on YouTube on this subject.

Sounds like a pooped battery and a short in the fuel pump wiring.

Inspect the harness visually. Maybe it's being pinched by the tank.


After you replace the battery check your charging voltage but if it had failed high your bike wouldn't have lasted several months lol

Thank you very much WIBBLY & WAZOO, I'll do so and report back. Not with the bike for another week or so but I hugely appreciate the advice.

+1^. Just figured it's a good idea to eliminate R&R 1st since tracking down intermittent shorts can be difficult.

What is a R&R?

Where and what would be pinched by the tank?
