Blown main fuse
I am having trouble with my main fuse every time I put a new fuse in it blows out immediately as soon as I put it in .I’ve gone through the whole wire harness & I could not find a short anywhere. I’ve even replace the whole wire harness with a new one and the fuse still keeps blowing out. If I unplug the voltage regulator the fuse will not blow out but once I plug it back in the fuse Will blow out. Can anyone help me with this please

Re: Blown main fuse
Sounds like you may have a bad voltage regulator, check the wires going to it, or replace it.

Re: Blown main fuse
I have already replaced the voltage regulator with a new one. I’ve also replaced the ignition as well as the whole main wiring harness.

Re: Blown main fuse
The main fuse goes to the ignition switch, the decomp controller and the voltage regulator. It then goes out of the switch to the box to power the rest of the systems it also has a tie point to the voltage regulator. Did you check the fuse box for a short when you replaced the wiring harness?
I gather that it blows the fuse as soon as you turn on the ignition. If so it has to be an issue with the ignition switch, the orange wire that goes to the fuse box, the orange black wire that goes to the regulator or the fuse box itself.
It does boggle my mind that disconnecting the regulator keeps it from blowing especially since the wiring harness and regulator has been replaced.

I can't seem to win the lottery. I think I have used up all of my good luck riding motorcycles.

Re: Blown main fuse
Unless he has gone with an OEM RR there's a real possibility the wiring pins in the connector block are in the incorrect location. There's a stack of Chinese RR's all over the place (not just eBay) that are generic in their application and whilst they say they'll fit your bike it's not always straight plug and play.

And he doesn't have a decomp controller.

Re: Blown main fuse
Instead if going through a bunch of fuses
Connect a light to the fuse holder in place of a fuse
When you locate the problem the light will go out or at least get dimmer
Or try and find an old seat belt buzzer then you wont have to stare at the light while working
And it replaces having to ask some one to watch a tail light while working under the dash
