'89 911 3.2 liter. Voltage is REEEALLLY low! Cant believe car even starts. Battery shows 10.8v when car off, 10.0 when car on and accessories on. Revving even to 3000rpm does not increase voltage at all. Battery light flickers on and off. Battery is 3.5 years old, Alternator is 17 years old. Time to replace alternator, I assume? What's the right part # for this car?

This link is for alternator choices for the 3.2L Carrera, don't forget to buy a belt while you're at it!! Make sure you inspect the fan housing mounting points VERY closely for deterioration and cracks. If the housing is cracked replacement is recommended. Another sign of bad fan housing is scratches inside the fan housing from the fan/alternator assembly scraping the fan housing.

Have the ALT rebuilt. Much better option

Yes, could only need the voltage reg and brush assembly.

I'm a noob. Freely admit it.

For $240 or so, it seems a wash just to buy a rebuilt one and install it myself, rather than take out the old one and send it somewhere to get rebuilt.

And, I'm in ATL, GA. Any recommendations on people who rebuild 911 alternators?
