If turning on the ignition causes the main 20A fuse to fry, then focus your efforts on the part of the electrical system downstream of the ignition switch. Something there is shorting to ground. Could be the switch itself.
Trail Tech, heated grips, aftermarket headlight (which blew its 5 amp fuse and then it’s bulb a few days before the current problem).
PO removed all the stock instruments and faring/headlight.
Most of the aftermarket stuff is connected directly to the battery,
The bike had been running fine except for the headlight problem until it blew its fuse ...
I wasn't aware of this. With all that extra stuff he could have burned out his regulator since they aren't made for high wattage. Plus a bird nest of wiring running here, there, and everywhere. Take off all the doo dads and start with the basics.
A guy from the Toronto Chapter of the ADV Forum who knows what he’s doing has kindly volunteered to take a look at it tomorrow.
I’m going to stop now so I don’t make it worse ...
Will update, thanks again
