the start button is pressed, the white/red wire is hot and goes to the starter solenoid) - from the accessory plug to another splice where it splits into two more leads - one goes to the front brake light switch where it again splits - goes to the neutral and temp lights - the other wire goes to the tail light, splits and goes to the rear brake light switch, splits and goes to the CDI unit

I'll bet the plug at the LH handlebar switch that has the red/black wire has a poor contact and is the cause of the loss of all power
So I took off the first plug and tested all the little connections and the one with the white wire only has 0.1v.I traced it all the way back to the starter solenoid and the side that the wire is on the solenoid won’t even go above 1.0v.Could a bad solenoid cause no power till the full machine ?
