Captain Chaos Posted November 4, 2017 Share Posted November 4, 2017 overcharging? Should be 14,5V at the battery, regardless of revs and lights on/off, never more. Quote Link to comment
wraith Posted November 4, 2017 Share Posted November 4, 2017 The high beam is the weaker part of the bulb and what may be happing is the small wire on the high beam is corneting to the low beam and over loading that ? May also be a bad wire posable head stock area? Try riding with just the low beam on with new bulb and see if it still blows. Also headlamp is not lose and bouncing about/coursing more vibrations?

johnr Posted November 4, 2017 Share Posted November 4, 2017 get a multimeter, measure the voltage at the battery with the engine off then with the engine running and the lights on. anything over 14.5/15 volts is bad. Quote Link to comment
