Voltage regulator HELP

Can anyone tell me where to find a voltage regulator for a 2001 Boxster?

My car is not holding a constant voltage and it is surging up and down about 200 RPM. While at the same time all the electrical items pulse up and down with the RPM. The battery checks out and this is my next option.

I am also getting the code “9133 61 term low engine running” any ideas or suggestions for further diagnostics would be greatly appreciated.

Thanks

The voltage regulator is part of the alternator and can be removed / exchanged quite easily with an aftermarket part once the alternator is out. On a 996 not a very difficult job. Don't know about thew Boxster.

Good luck, JP

Where did you get your voltage regulator? The guys at my dealer can’t seem to find a part number for it.

This is the one I purchased for my 2000 Boxster S.

Im also having a charging problem: had the alternator checked at Advance Auto and it checked out ok, but when I start the car and remove the neg terminal it goes dead sometimes...sometimes not. Also a P 0650 pending code. Seems like an electrical problem as the car runs until it kills the battery but no battery light. Sometimes it charges and runs ok after I recharge the battery...anyone???

Thanks in advance!

You likely have a bad ground or bad alternator.

Never remove the battery terminal when the key is on or engine running. To the original poster- perhaps you don't have a charging system fault if your idle speed can't be controlled. Check for vacuum leaks and clean the throttle body/idle speed motor.

Or a bad connection where the cable form the alternator connects to the engine (the bolt behind the little black door, for lack of a better description).... I had this happen to me and ended up unnecessarily replacing battery and alternator. ;-(
