  1. First of all thanks to Ahsai for the post on the wire and inspection mirror in order to access the rear of the alternator. Same story as many others here, 14v at start up and as the car warms, drops to 13v (with nothing running). Dash volt meter drops to 12v with lights, a/c on, but actually measures 12.7v at jump start post and battery. I replaced the voltage regulator 9 months ago, appeared OK for 3-4 months. During the summer the problem re-occurred. I read many posts on other's problems. When the engine is warm, the voltage drop from the back of the alternator to the +ve post in the engine bay (jump start post ?) is 0.8 volts, obviously way too high. Car is a MY 2000 911 C2. There appears to be 2 different harness images posted from the various discussions, so I'm trying to figure out am do I need to replace the Y cable #28 or #21 from the respective images. Also how difficult is this after the alternator is back out? Hoping not as bad as Equinox 997 post. Is it the same as Ahasi's description in this link? http://www.renntech.org/forums/topic/44682-how-do-i-replace-the-cable-from-the-alternator-to-the-starter/ Thanks Mark
