My kymco super 8 headlights go out when you open the trottle and come back on when the bike is idling
There are three possible sources of power. 1. The light control assay is a module that determines when to cut power to the lights when at idle or starting the engine... it can fail and prevent power from going to the lights. 2. The CDI. It sends a signal to the Light Control Module... if no signal, no lights. 3. The light switch. The wires can get lose and prevent power from going to the LCM. Start at the Switches. Test for power from the switch, if no power from the switch, make sure power is going to the switch. Flip the switch from low to hi beam too, test both lines. The CDI is a bit trickier to test but there is a wire to the LCM that can be powered when the bike is running (a bad CDI is diagnosed after everything else though as it is difficult to test and very unusual to happen). If power is going to the LCM, that rules out the switches. If you confirm power to the LCM, and power from the CDI (a signal from it at least), then its a bad LCM. But check your light bulbs before doing anything. If you bypass the LCM on an American bike (connecting the blue wire to the LCM to the blue wire from the LCM together), it will blow the fuse but some European and Phillipine models work without the LCM. LCM's and CDI's aren't cheap so have a professional confirm the parts are bad before replacing.
