Ok, I have been reading up on regulators/rectifiers, and here's my situation. My voltage regulator went out on my 98 wr 400. I have decided to replace it with a regulator/rectifier because I am in the process of making the bike street legal, and I need DC for the turn signals. I have a regulator/rectifier off of a wr250 that I am trying to wire up. I have both the wiring diagrams from both bikes. The regulator/rectifier has 4 wires-yellow, white, red, and black. The white and yellow go to the stator on the wr250, and the red and black are the DC + and -. As all you guys probably know the wr400 stator is chassis grounded. I ran the yellow wire to the wr400 stator, the white to a chassis ground, and the red and black are my DC ground. I have the regulator/rectifier insulated from the chassis in the air box, and my DC ground is not grounded to the frame, it is grounded to the regulator. I am not getting any voltage out of the DC wires. The bike starts and runs fine though. I connected the regulator/rectifier to the stator via and chassis ground via the stock tail light connectors. The stock voltage regulator is taken off of the bike, so that terminal is empty. I don't think that that should affect the regulator/rectifier though. Anyone have any ideas?
