I guess I should have said ignition switch, it looks like it has a brown tail by itself off the switch. Can I test for a short in the r/r. Thanks
A difference in the ignition switch could be the problem. That's where I would start my troubleshooting.
I just dug out my 750 diagrams.
Are you saying you are using a 750 ignition switch?
If so, the brown wire from the ignition switch is what goes to the brown wire of the reg/rec. It also goes to many other things. The ignition gets its power from the yellow wire coming out of the ignition switch. When the key is off, the brown wire has no connection to the yellow wire. It wouldn't matter if the reg/rec was shorted, in that case. The ignition should shut off when the key is off.
The brown wire and the yellow wire get their power from either of the two white wires going to the switch. The white wires are hot from the main fuse. When the key is off, all wires are unconnected, in the ignition switch.
If you are using the 650 ignition switch, the brown wire feeds the ignition through the kill switch. In that case, then the reg/rec needs to be looked at (along with other wiring possibilities).
Even though it's possible reg/rec is shorted, I wouldn't think it would be likely that the brown connection is internally shorted to the white. A lot of things would have to go wrong (assuming it was wired internally, correctly, in the first place). However, if the ground connection on the reg/rec was not good, it may be possible. Check the ground wire from the reg/rec to the battery to make sure it's not broken. The ground wire to the reg/rec does handle significant current.
To test the reg/rec, disconnect the white and brown wire from the reg/rec. Then run the bike. The white wire on the reg/rec should have 15vDC or higher (possibly much higher). The brown on the reg/rec should have voltage much lower than 15, if any voltage.
