i'm stumped and hope that one of you guru types can help. my boy smashed the headlight on his cg125 in a low speed spill. i've fitted a complete headlight unit but gremlins have attacked. every light, indicator, horn etc works until i connect up the little pilot light. once this is connected, all the main lights go out, including the instrument lights (indicators, horn, and dash warning lights still work fine). pull the connectors apart for the pilot light and everything else works again. any ideas please?
