hi, the bike has been stood for about 4 years before this it was running. i have stripped it down and putting it back together at present i checked the old loom was a bit messy instead of sorting this i bought a second hand loom of a working bike all connectors are fine and cleaned new relays and starter solenoid, problem is it keeps blowing the main 30 amp fuse only thing i can think of is the main wire from starter motor to soleniod as this is the only thing i havent changed any ideas wot be very greatful thanks in advance

the only time i have had fuses blow is when there is a short-circuit somewhere, V=IxR voltage is fixed 12V, but a short causes R to drop, which causes I to rapidly rise, blowing the fuse.

I would be checking the areas around the starter relay, starter motor, battery terminals for possible shorts...

Is there anything that your doing when it blows?

i have checked and cleaned all earth points and it blows as soon as i connect the battery

In my experience a fuse will blow in case of a dead short. In other words a power wire that is making a connection with an earth source. Quick question though, can you please post a pic of the fuse. I am busy putting my bike together and I am having trouble finding places for all the plugs as well as which type of fuse to use (blade fuse ect).

Its definately the right size in there?

Make sure everything is turned off, lights indicators etc. Better still disconnect them altogether, even the switch gear. That will eleminate those things at least. Check you havent snagged the loom on the frame, a bare wire shorting with the frame will be sure to blow a fuse.

think i have found the problem starter solenoid is knackered
