Hi My charge light keeps coming on and dissapearing! if it comes on i free rev it to about 4500Rpm and it goes away only to come back on shortly, fan belt is tight but it hasnt been replaced for ages, so i am thinking its that, otherwise if the alernator was stuffed it would be on all the time and not dissapear when i rev it to 4500Rpm sometimes 5000RPM and seems to go out when i also brake or stop.

Can anyone give me an idea on what too look for or if someone has had the same problem.
