I've had it in the motorcycle shop for 2days now, and they cant find the problem. They can not find a short anywhere. The main fuse blew 4 times in a roll on me but now they said it isnt blowing any now. they said more or less nothing we can do. One guy there said buy the whole electrical harness thats like 500 bucks. I dont know what to do. DD

Re: Update on the main fuse blowing
I wouldn't bother with buying a new wiring harness, if the fuse is not blowing now I would be asking what Amp fuse they are using. It is possible you were using the wrong rated fuse for the job. I would be looking for wear marks on the harness, usually these things happen becaus of constant rubbing causes a short which is hard to find, a good auto-electrician should find it.

Well that is a big problem... Check the main battery cable to see if it is accidentally grounding anywhere. That also goes for any cables coming from the starter solenoid. If you're blowing the main fuse it is likely something big. I mean what is that like a 30amp fuse?
Direct short in the main wiring that the main fuse protects. First disconnect the regulator connector and see if the fuse still blows. If it is not the regulator you will need to inspect and trace the main wiring to find the short. A re-settable circuit breaker of the correct amperage is a great tool for this to substitute for the main fuse otherwise you may need a lots of main fuses by the time you locate the short.
Usually a bad regulator will only cause problems with charging... Sounds like you've got a short somewhere in the wiring...I'd start by checking the ignition switch wiring and the connections going into the fuse box.
Its either in the alternator itself which would be a shorted circuit or a short in a wire.
The only main fuse is on top of the solenoid.
There is a white wire which goes to the voltage regulator. If thats not touching ground anywhere, you need to check the voltage regulator or alternator , one will be shorted if the white wire isn't.
Hi ...... Could be almost anywhere. Have you recently had any work carried out ? Gonna be a 'long' process but try with ignition off, change fuse, and one after another disconnect main/plug connectors in the loom ................ with any luck you'll isolate the problem to a section of the loom or component. You may need a few fuses. Finish off with a multimeter.
Let us know how you get on.
To my knowledge, there are no onboard electrical/electronic components capable of shorting and blowing the fuse with out blowing any of the secondary fuse. The main fuse could possibly blow due to a short in the wiring or an exposed/frayed wire touching the body. The three most likely areas would be:
wire harness leading to the regulator;
wire harness leading to the fusebox; and/or
wire harness leading to the ignition switch.
Just a start, do postback how things turned up or should you need additional information. Good luck and Thank you for using FixYa.
