Porsche 911 (1965-89) Alternator Replacement

One of the nice things about the configuration of the 911 engine is the relative ease with which you can replace the alternator. The alternator is located directly in front of the fan: a great location because of the amount of cooling air it receives. The replacement and repair process is straightforward, and should take you about an afternoon to complete. The first thing that you need to do is to make sure that your alternator is indeed the cause of the problems with your charging system. Sometimes bizarre electrical problems can be caused by a number of faults other than the alternator. It's important to troubleshoot the system prior to replacing your alternator. The first thing to check is the fan belt. Is it tight and amply turning the fan? If not, then retighten it, according to the procedures outlined in Pelican Technical Article: Fan Belt Replacement. Modern fan belts rarely break, but they get brittle and glazed with age, and can slip on their pulleys. Replace it with a new one. The next item to check is the voltage at the battery. This should read a little more than 12 volts with the engine off. When the car is running, the voltage should read at in the range of 13.5 to 14.5 volts with the engine at 2000 rpm. If your battery appears to be leaking, then your voltage regulator has probably failed. The battery will usually only leak acid if it has been overcharged at a much higher voltage. If the voltage measured at the battery is more than 16 or 17 volts, then the regulator is probably bad. If your battery has boiled over and has acid overflowing out the top, make sure that you clean up any spilled acid immediately. Dousing the area with a water and baking soda solution should help considerably to neutralize the acid, and prevent it from eating away at the metal. An important item to check on your car is the transmission ground strap. The engine is electrically isolated from the chassis by rubber motor mounts. If the transmission ground strap is missing or disconnected, then you might have a whole bunch of problems, including electrical system malfunctions and difficultly turning over the starter. See Project 87 for the exact location of the transmission ground strap. All 911s up to 1981 had external regulators and from 1982-on, the alternators had built-in ones. If you've determined the regulator to be working properly, then you should probably remove the alternator for testing and inspection. Before starting any work, make sure that you disconnect the battery. The positive battery terminal is directly connected to the alternator, and it can be dangerous to work on if it's live.
