So I took the alternator out and dropped it off at an automotive electrical repair shop.

They indicated the pulley clutch felt warn out.

Anyways, will wait to see what they determine is the problem.

Car is 6 speed, should it have a clutch pulley?

Yes there has be be a clutch if you got 6 speed.

+1 and a hand twist test generally gives a pretty decent idea if its good or not

Pulley clutch in an alternator?

993GT

yes used on manual trans. cars to extend belt/component life by not decel shocking.
The pulley freewheels in the reverse direction

Typically, when you purchase a rebuilt alternator does it include the pulley or do they expect you to transfer the old pulley to the rebuilt alternator?

993GT

typically comes WITH a new/rebuilt pulley

You are the first person I have met that knows why a clutch pulley is used. Thanks for the info.

Finally put the rebuilt unit in. Bearings, pulley, regulator.

At idle with just daytime running lights on I am at 13V.

At idle with everything on, low beam, high beam, wipers, blower, heated seats at 12.3V.

Took it out for a boot and wow how I have missed her....I have been driving a 2001 Golf TDI for the last 2 wks.

so everything is back to normal, nice.

Punko - those numbers are low, mine with everything on is above 13volts at idle, and with just lights on is around 13.8 volts. You may want to put a volt meter on the battery terminals themselves and see if your gauge meter is correct, if so you may want to see if your battery is up to snuff.

Regulator sometimes does strange things. Also the onboard indicator is not the best but I agree, a check with a voltmeter should give you more accurate vale!

I thought they were low myself glad to see I still remembered correctly=good info.

Thanks for the posts.

The measurements were at the battery!
