Hi

I really need some help..I have been biking for 30+ yrs and know my way round a bike, but have encountered an electrical problem that has me stumped!.

Riding down the road my 10k km nsr MC21 decides to blow it's 15Amp Ignition circut fuse..3 months later still not sussed the problem!

The fuse doesn't just blow it lasts about 10 secs then the oil flight flickers indicating its up to something and pop goes another fuse!!

i noticed the pgm box gets good and hot so must be trying to do something..it's not the rc vave motor or the kill switch..and assume its not a short or surely the fuse would blow immediately..

Does anybody out there know something i don't?!!..Any advice GREATLY received..cheers Tim

regulator/rectifier not doing its job properly maybe?

why dont you try doing a test with a polymeter?

When the current is close to the fuse rating, the fuse will take some time to blow.
10 sec. , on a 15A fuse, would be approximately 30A

You should remove all current consumers from the wiring, put in a new fuse and then connect the consumers one by one, untill the fuse blows.

The tough method, is to put in a bigger fuse and wait for the smoke to show you where the problem lies
