I have a 1980 Sachs Sundancer, I Got it out of an old garage of mine. The motor will turn over, but someone has messed with the wireing. They cut the wire harnes after the wires come out of the moters. Parts of them our just plan missing. There is a blue, black, and yellow wire coming out of the motor. The coil has two terminals. At this point I just want to see if I can get it started. I can handle most of the rest. Does anybody know what I conect what to..
