Not too difficult it is true. The alternator is back together now and I have been trying to test it (there are several Youtube videos on how to do that) but I am getting no voltage to the attached battery. I suspect the the drill that I am using to rotate the rotor does not turn fast enough. I calculate that the alternator turns about 2.5 times the speed of the crankshaft so at an idle of 700 rpm the alternator should turn at 1720 rpm. My drill gives about 1200 rpm. So I am trying to think of a way to get it to turn faster with what I have available.
Because the pulley I took off the alternator was seized I decided to verify the pulley on the alternator that is installed in my base Boxster that I am selling... and found it was seized also, so I bought a new pulley and installed it in the car. When my Boxster S comes out of winter storage I will check its pulley also. It seems that that is something worth doing when the front cover is off the engine.
