Well Mr Retiredgentleman, I tried as you said to do. I added another ground wire jump from the battery to the frame. I am a master electrician so its really upsetting to feel as stupid as this bike has makes me feel. The reg rect has good positive to the blue and and the orange wire has a good ground. I still am still getting high volts at the battery. Am I like you suggested in need of a new reg rect. I guess the only reason I'm kind of asking twice is the part was supposed to be new and we changed a few wires around the other night with my friend here helping me. I have ungrounded the brushes with the nylon screws. Checked the a/c voltage out of the stator on the three white wires. Seems to be good. My red is getting 12 positive volts to the red brush when the key is on. Does it still sound like I need a new rect reg? I appreciate your help so much, thank you all stan
With the 70 to 79 charging systems (stator/rotor), using a 70 to 79 type of regulator, there is no need to use nylon screws on the brushes. With that type, the right (inner) brush is grounded, with the brush screws directly screwed to the stator housing. The left (outer) brush, of course, is insulated from ground.
I'm not familiar with the 70 to 79 combined rec/reg unit. Was it purchased from Mikesxs, and is the stator/rotor also from Mikexs? xsLeo had posted the colour code for the wires of the Mikexs rec/reg, so that is my only knowledge of the proper connections.
A few questions.
The blue wire of the rec/reg is the reference voltage input. It should be connected to the immediate load side of the ignition key. That is the same brown wire that feeds the input of the fuse panel. Are you connected to that location? If you are connected to somewhere else that has lower voltage then that would cause the regulator to raise the voltage to 16 as you have seen. It would be interesting to know what voltage you have on the blue wire, when you see 16 or more volts at the battery. In other words,if you had a large voltage drop across the main fuse and/or the ignition switch, that would cause the regulator to drive up the voltage to the battery.
You say the orange wire has a good ground, but according to the information from xsLeo, the orange wire from the rec/reg supplies a positive voltage to the left (outer) brush.
You also say the brush with the red wire is getting 12 volts +, whereas my information says that red wire is on the right (inner) brush which should be grounded to the stator frame. My information shows the green wire from the rec/reg, connecting to the red wire that goes to the right brush.
Do you have any wiring instructions that came with the rec/reg and stator/rotor? I'm sensing that you or the PO have not connected the wires correctly. To many ways to go wrong without manufacturers wiring instructions.
If my info is correct, you need to have the green wire from the rec/reg connect to the red wire of the stator (right brush) and that right brush must be grounded ..............no nylon screws. Also the orange wire from the rec/reg must connect to the green wire of the stator (left brush),and that brush must be insulated from ground.
Here is some more reference info:
With the engine idling at 1200 rpm, you should expect to measure 12.5 to 13 AC volts across any 2 of the white stator output phases, with the harness connector connected as normal.
If you measure the DC voltage across the 2 brushes with engine idling, expect 12.5 to 13 volts.
With engine reved up to 2500 to 3000 rpm, expect the voltage across the 2 bushes to decrease to 5.5 to 7 volts.
