blowing headlights and tail light


Recommended Posts

First verify that the voltage regulator is plugged in.  Small silver box mounted next to CDI.  If plugged in, unplug lights, set multimeter on AC volts and connect to tail light wire and ground.  Run bike up and see if voltage exceeds 15V.  If so, voltage regulator is faulty.  Do NOT plug headlights back in until you run this test again and confirm voltage stops climbing around 14.5-15VAC.

If you just rebuilt it I am guessing you unplugged your regulator. Check all your plug ins and I bet that will fix it. The voltage regulator is the little one wire box that hangs on the rear subframe next to your CDI box just in case you dont know.
