My friends cfr 150 has problems.he has completely destroyed the wiring harness and now he has come to me for help. I am an ASE cert holding auto mechanic but I don´t even ride much less work on bikes (this will be my first) I have tried to do some on line searches for schematics and other information but it seams that Honda is a lot more tight lipped on their power sports info than their automotive. My friend has purchased 2 different aftermarket control boxes and says one is AC and the other DC but he doesn´t know what the original was. I thought all ignition was DC . Someone please cure my ignorance.
