Answer
Hi Tracy...

The C70 Passport is a very simple 6volt electrical system. I assume that the bike does run, but that you are kick starting it? Based on everything you have said, I think your problem will be found where the wires for all affected circuits join. The passport has only one fuse, and ya know it is good... so the problem is gonna be between that fuse and where the wires branch off to the other circuits. Also check the main ignition key switch, but if the bike runs, the key switch is prolly not the problem. Use a test light to make voltage checks with the key on. I'm betting that there will be an area where a group of wires are crimped to a main "feed" wire, and that connection is prolly bad and/or corroded. Good Luck Tracy.
