    That's trouble. Recheck connections. Use Deoxit on the plug-in connectors. Use fine grit sandpaper (and clean off the grit left by sanding) on the nutted connections. Is it possible you shorted something out as you removed the battery? Were the battery cable ends removed at the battery? Is it the original alternator? It might be possible that it's only the voltage regulator module.

    Your alternator is not functioning, running you should have 14.5V DC. Pull the alternator, check the wiring connections to be sure they are tight and seated, if they are you are in the market for a voltage regulator..........

    I'd start with checking the alternator, is it putting out 14.5 V DC at idle? If not, I would check to make sure you properly reconnected the wiring.

    What are your voltages? Resting, idling, driving above 2000rpm? There are gizmos to help with this monitoring - Antigravity Batteries has a battery tracker. Others plug into the cigarette lighter. Do you have any codes (can be read with Durametric and other (OBDII) readers)? I've read stories on Rennlist about induced electrical noise in the sound system even when the sound system is not turned on. Might your alternator be damaged or no longer have a high quality ground? Could the noise be mechanical (transmitted noise)? You did change pulleys. Run the car a few minutes without the serpentine belt and see if the noise is reproduced.

    Because it is a 2005 engine, it would most likely have the oversized third generation IMS bearing in it, which means it cannot be removed without total disassembly of the engine because it will not fit through the opening in the engine cases. One way to know for sure would be to pull the trans, clutch and flywheel off and look at the nut on the IMS bearing center bolt; if it is 22 MM, you have the oversized bearing, which was the only one to use that large a nut.

    The engine serial number would have been built in late 2005 or early 2006. Porsche rebuilt engines always get the latest parts and a warranty. To be sure you would have to open the engine to get the IMD diameter. If you want insurance then you can install one of the 3rd party IMS oiler solutions. IMS Solution: Oil Fed Plain IMS Bearing - No Ball or Roller Intermediate Shaft Bearings LNENGINEERING.COM IMS bearing failures are expensive. The IMS Solution is the only permanent solution to the IMS problem. Proven protection and the industry’s best warranty.
