Fuse problem.....AHHHHHHHH

[Judgekane]

Right 1st Hey guys how we all doin? :cool:

I have a sv650s K1 (51), the speedo drive has given up the ghost when I changed the tyres, DOH 8-[

Now it keeps blowing the fuse that handles the 'dash' lights, rev counter, indicators and rear lights, I have tried with the 'broken' speedo disconnected and with my lights off and it still happens, always at random....:smt074
The new fuse lasts anywhere between 5 mins to the next day!!!!!

SOOOOOOO before I delve into the harness is this a common fault or has anyone else come across the same prob? :confused:





Also, ;), if someone knows where to get a cheaper than £50 speedo drive....:notworthy:

I bet you shiney english pound that the wiring loom is rubbing against the frame somwhere. Places to check

1. Around the headstock
2. Where the loom disappears under the tank / airbox
3. Where the riders seat is, the bolts that hold the seat on can rub onto the wiring loom
4. In and around the rear plastics, sometimes the loom rubs on the subframe.

HTH

I am having a similar problem except my fuses never last more than about 30 seconds.

But i am puzzled as to how this would cause the fuse to keep blowing. Is it just if the wires are touching something or is it because the wires are being "pinched".

Because if the wiring is chaffing, then a live wire may have had the insulation worn off it and be shorting to earth on the frame. The most common cause of fuses blowing is a short circuit. If your fuses are blowing almost immediately then it is almost certainly a short circuit.

Have you actually checked the unit, they are easily broken with ham fisted wheel replacements.

remove the blown fuse and connect a bulb across the terminals which will light if there is a short. then its just a case of disconnecting things till the bulb goes out and hey presto you found the faulty component

mine was faulty front sidelamp bulb holders. the above method will make things very easy to locate the fault..

hope this helps jon
