Gsxr blowing main fuse - 2006 Suzuki GSX-R 600

Remove your seat and in that compartment you'll find your battery and right next to that(depends on what year your bike is)will be another fuse box with a 30 amp fuse in it..Inspect that fuse box for continuity and replace the fuse..When I had a Katana that's what I did and also found the same fusebox in a similar location on my 98 gsxr 750(SRAD)hope this helps..

beside the baterry

No...but you burned out the main fuse. look by the starter..you will see a red rubber type boot...under it is a fuse..replace it

the starter may be getting wore and the bearings and brushings getting tighter causes overheating when trying to start.

rectifer and alternator need checking !

No but this should be an easy one to trace the problem since its the one hot lead from the battery to the switch. follow it and you should be able to find where it grounded to the frame pay a close attention around the steering area where the wires come from the farme to the ignition swithc.

Rather than the fuse, pull the negative battery cable....

You need to locate the main fuse. It may be in the main box with the other fuses. On the bikes I am familiar with they put it on the starter solenoid. Your owners manual will tell you where it is. If the main fuse blows you lose everything. The only other thing that causes the condition you mention is a broken connection in the battery. Testing the cells shows a full charge but no juice comes out. You have to load test the battery to find out if the battery is bad. You could jump the bike from another battery(with the other vehicle turned off)if your bike lights up , this would tell you your battery was broken internally.

Check for blown fuses.

My guess is the wiring around the headstock pivot are shorted out, and you will need to need to do a check with a meter. This manual should explain clearer....
