Just completed installing a new wiring harness on my 1968 Honda CT90 K0. Everything works fine EXCEPT when I turn on the lights, the head light works as it should, but the taillight goes into stop light mode with both elements lit. When the lights are off the brake light works as it should. Could the issue be with the right handlebar switch? I am at a loss!
