Running out of electricity

Recommended Posts

Hi all, I have taken the plunge and picked up my 1981 S3 N/A yesterday. It is alot of fun.

However, I seem to be running out of electricity on it - by that what I mean is when in heavy traffic, with the lights on and cooling fans running, my voltmeter slowly drops from above 13.5 down into the red and I have to periodically switch of the fans / lights and wait from the voltage to creep back up - the idle also gets pretty rough at this point as well. Is this because the Esprit does not like being stuck in traffic (perfectly understandable) or do I have an alternator / voltage regulator issue? NB the car idles at 1000rpm when warm (rather lumpily).

It does sound as though you you have an issue with the charging circuit, and it could be the alternator as you suggest. As the dial on the dash can be a little bit inaccurate, I suggest you put a meter across the engine without running and with the engine running, you should get approx 14v when running, if not it could be the alternator itself, or a slipping belt, or maybe a corroded terminal somewhere.
