Hi All,

Have a problem with the back tail light dimming when the engine is reved, i think it might be the regulator but the front lights are not dimming! does anyone know if the front lights go through the regulator as well? if they don't i wouold guess it the regulator / rectifier thats gone. Whats everyone think

Many thanks
Paul

It could be a poor connection. Revs make vibrations and that might be making a poor connection worse.

Hard to say with no information about your bike...

Put a dvom on the battery and see if the voltage drops when u whack the throttle. Your looking for a signicant drop also 9.6 to 10 volts. If it does the ignition system is pulling the voltage to fire the ignition and this would indicate a weak charging circuit. Also check your battery static voltage 12.2-12.4volts. 13.4 to 14.2 approx when running. Our take 2 sec. and have it tested. Also like u said check all connections at pwrs and grds. good luck:thumbsup:
