I put what I believe to be a 1974 TL125 back together for a friend. Everything is working okay until I rev the motor and it blows both the head and tail light bulbs. It has two wires coming out of the magneto. From looking at old wiring diagrams on line, I found that the white with the yellow stripe is the lighting wire. Went on ebay and found a 6 volt selenium regulator/rectifier listed for a TL125 and purchased it. The problem is that the wiring loom has been butchered over the years and there is no plug for it. I can just wire it into the system but don't know which wires on the regulator to use. Anyone have any experience with this or an electrical engineering degree that can help me out? I've included a picture. Thanks.
