What's it mean when this light comes on but the alternator is working okay?
Bloke at work's motor. The voltage across the battery is 14V with the engine running but the charge light just about glows. The more electrical load you bung on (lights, fan, wipers etc.) the brighter the light glows.
Otherwise everything is fine and the battery stays charged up, so it looks like it just THINKS there's a problem.
I've had this recently, light glowing very faintly. Put it down to the belt slipping really bad, then it squeels which I take to mean the belt is trying to grip and the light goes out meaning the belt has gripped.
Best bit is when the squeel has gone and the light is out meaning all is well
