A bigger alternator pulley would make it spin slower not faster. Maybe it was just spinning slower and not fast enough to charge properly ? Spinning an alternator faster shouldn’t cause overcharging as it has a regulator built in. That’s until you reach the point where it mechanically fails though spinning too fast.

In the end it was actually the pully wheel on the alternator arm that was the problem - the new alternator had one that was significantly bigger than the old one and that's what was causing the overcharge (spindle turning too quickly). But that's just my experience, good luck with the refit. On Thursday, March 7, 2019 at 7:22:19 PM UTC, Jamest142 wrote: Hiya folks Q2-002 is in disgrace at the moment... As well as a burst heater hose (to be fixed when it is dry!), she is having charging issues if anyone can offer any advise please? The charge light is on very dimly most of the time at all rev speeds, when running with no load the voltage is 13.9-14.1V, when the headlights are on it drops to 13.2V or so. If I put everything on (heater fan / fog lights / brake lights etc), then the volts drop to 12.5V or so. If I charge the battery over a weekend, and leave over a couple of days (it is my daily drive so can't leave longer!), then the battery holds the charge, and does not seem to significantly drop. When on tickover at 800rpm on the rev counter, the volts drop down to 12.7V or so, but go up when revved very slightly. Finally 2nd strange thing, when I 1st start the car, I have to rev up to 2000rpm to get the red light to turn off / go dim. I have had a new battery and a recon alternator with the original pulley wheel last year. These were changed as I the battery was going flat, and thought these were the issue, but the original setup did not have the dim ignition light issue... Can anyone advise if it is a duff battery, or duff alternator, and is there an easy way to check? Or any other suggestions please? Is it worth taking a wire directly from the alternator to the battery?
