I am currently in the process of restoring a 1974 Full Dress Honda CB350 Four that has been sitting since 1979 and well the only thing thats keeping me from riding it is the tail light... it will not come on with the headlight, but if i turn the ignition to park/accessory it turns on and the brake light works... i just cant figure out whats causing it to not turn on not to mention its kinda hard to trace the wires throughout the bike to figure out where the problem is, so if anyone has any suggestions i would really appreciate it
