2 hours needed to change alternator:
- disconnect battery.
- remove top covers of engine - behind front seats
- remove 4 plastic bolts to remove side cover.
- remove all of the bolts to remove metal cover
- losen belt by putting a 24mm wrench on tensioner and turing CCW. You should also consider changing the belt ($18)
- remove the alternator screw and the flywheel screw beside alternator.
- move the alternator up on the flywheel screw side. If stuck use a hammer and wedge to move it up until it losens.
- remove wire and plug.
Rebuilding the alternator. Only 4 things can be wrong:
1- bearing worn out - turn rotor to test.
2- coils short - smell and check for burning in side.
3- Rectifier - take plastic cap off and test with an ohm meet from the heat sink to each of the 3 diodes, then reverse the testing points. If both resistances are the same on any of the 3 diodes, replace rectifier.
4- If the top 3 are fine, then it is the regulator. This is a hard part to find retail. Ebay and other sellers will try and get over $100 for it. Porche claims they don't sell. It was found at a wholesaler, who sold it for $17. 2 bolts and one screw and 5 minutes later and it was replaced.
To reinstall follow the reverse. Remember the flywheel part of the alternator goes in on the to of the backet. you may have to use a hammer and wedge to get it down. Install the flywheel before it goes all the way down, or it will be difficult to slide in.
