problem with my 2006 Porsche 911S
I posted a problem with my 2006 Porsche 911S regarding the message I get on the tach display that says "check generator or battery". The original engine had been replaced with the same 3.8L engine, but from a 2008 Targa S. I read a post about the wiring of the blue wire from the alternator to a different pin someone posted, but I don't think that any wiring changes were made on different yeas of the 997.1 models. I looked at schematics for 997.1s and they were for 2006 to 2008. Maybe the wire pin was changed between an 2005 996 and 2006 997.1. I don't think that is what is causing this message. The voltage on a voltage gauge I installed always reads about 14 volts at any RPM and the battery always seems charged so I don't think anything is wrong with the alternator or voltage regulator.
I notice that the alternator part number changes in 2007 from the 2006 911 models all models of the same year seem to use the same alternator for the manual transmision and the pulley is fixed whereas the pully has a clutch for automatics. The 2008 alternator is more expensive than the 2006 but I believe both are 150 amps. My question is what is different about the 2008 alternator from the 2006 one? Could this be why I get the message since I was told the 2006 alternator was not replaced when the 2006 engine was installed? Any ideas? __________________ This post was auto-generated based upon a question asked on our tech article page here: Porsche 911 Carrera Alternator Replacement - 996 (1998-2005) - 997 (2005-2012) - Pelican Parts Technical Article |

The pulley on an automatic is fixed. The pulley on a standard has a "sprag" clutch to allow over run when shifting. That shouldn't cause your problem. That said it might cause the brushes in the regulator to jump and cause some spikes that activate the fault light. It would be more likely to cause the accessory drive belt to squeal/wear/get thrown.
Watch the alternator in this video of first start of a 6 speed. http://rennlist.com/forums/996-forum/974606-first-start-videos.html
