I have an 07 wr450 that has had a lot of the electrics disconnected / removed. All it currently has is tail / stop light, head light and a Vapor speedo. I want to get it road legal and need to figure out where all the wiring and connections are for the horn indicators, neutral light etc. My question is can I hook up a 12v car battery to the rectifier output or similar location to power the DC system and enable me to multimeter check the wiring and switches when live. I am hoping this would give me power to check the system without having to actually start the motor all the time. Cheers.
