rectifier/regulator wiring help please
« on: May 05, 2015, 07:40:58 AM »
I received my rectifier/ regulator combo without installation instructions. I asked the seller to provide them but they said they just sell the parts and don't know such information. The harness includes 3 yellow wires, a red wire, and a green wire. Then there is two other wires outside of the harness, one is white, and one is black. Is there anybody that can help me with this? I sure would appreciate it, thanks in advance. Below is a link to the exact regulator/ rectifier I have.

Colors should pretty much match your harness already.

Yellow to yellow (alt. phases)
Black to black (bike power)
White to white (field coil)
Red to red (to battery +)
Green to green (ground/frame/battery -)

Just make sure the green from generator goes to ground, it's easy to just connect that to the regulator, and then it's no good. You can do it that way, but make sure the wire ALSO goes to ground or you'll fry the rectifier. In short: generator green to ground, reg/rect green to ground.

Yep. That one should plug right in to your harness where the old rectifier did, and then the two other ones should plug into the black and white wires that plugged into the old regulator.

You'll also have an extra green female spade connector on your harness that used to connect to the old regulator. The new one doesn't need it because it's already got a green from the rectifier plug. So just let it hang loose and don't worry about it.
