I am about at my at my wits end here. I have been having electrical gremlins. First my headlight and taillight weren’t operating. Figured out the headlight was that a connector on fuse panel needed replaced and repaired it. Started troubleshooting taillight when now I get a drop in voltage when I turn the ignition switch on. Hours spent troubleshooting so moved on to taillight. Problem there was cheap Chinese eBay taillight solder joints broke. I have unplugged everything and checked multiple wires. I once unplugged the rectifier and everything was normal again. But then moving back to taillight I hit hand brakes and problem came back with rectifier unplugged. Removed whole headlight bucket and wire harness from headlight bucket. Checked ignition switch and cleaned contacts inside where I was sure was the issue. I got it to duplicate the problem in the switch. I had the switch on reading 12 volts and started working. While one and reading 12v squeezed brake back to problem. Tried to wiggle ignition switch harness contractors and get switch to operate again no luck. Battery reads 12v in off but draws down voltage in on. Some other things I thought were the problem but turned out not to be. I turned the run switch to off and the voltage on dropped to 5v when I turned on ignition. I have unplugged hand brake, run switch, everything in headlight bucket except ignition switch still causes and issue. I am going to unplugged all harness in the rear again after I eat. Any one ever experience this electrical phenomenon? Is it just the switch and I’m about to set fire to the bike for no reason?
