I have a 78 z1R owned it since it was new. It's been sitting for a year since starting it. This past winter took off front/rear calipers and cleaned them, also cleaned front master cylinder. New problem, no head or tail light. Brake light, signal lights and 4 way flashers work. One element in tail light was burnt out, replaced it still no head/tail light. Metered all wires, seem good. Head light works when we jump wires (head light bulb good bench checked it. Any ideas, does it have a feature where when u hit start button it shuts down lights til it starts.
