Here is the situation:
I recently put a different motor in my 1973 Honda CB500-four, which has less miles than the previous motor. The new motor is from a 1972 so its basically identical. I also put in a new ignition switch as the old one was a bit worn along with a brand new battery. After getting everything reassembled, the bike runs great.
Recently the headlight, brake light (running light), speedo/tach lights and kill switch do not want to work. The brake light (stop light) does work when the brakes are applied. Everything had worked before I put the new motor in and I didnt change any of the wire connections in where they all come together in the headlight bucket. I have checked the resistance of the headlight and the test shows the headlight to be in working order. The electric start works fine (the button is in the same switch housing at the headlight switch). I have inspected the headlight/kill switch/electric start button (right hand side of the handlebars) and the internals appear to be clean with good contacts. The headlight switch on the bike has an; off, low and high position.
It is my understanding that there are two circuits on the bike. So the circuit which has the electric start on it, is working and allows the bike to run. The circuit that appears not to be working is all of the lights that should come on when the headlight switch is turned to the low or high position.
Has anyone dealt with this before? Any help is appreciated.
