I installed a new alternator after having the old one fail on me. The new one has the internal regulator on it. Purchased from our host. I put it back in just the way it came out, I believe, however, I am not getting the car to start. We're talking a 1977 911, 2.7 coupe. I had three connections to make plus a ground strap. Looking in to the alternator, on the left post, the + side, goes two red wires, on the right side, 3 brown wires, on the center post, most highest, looking in, a blue wire. The ground strap, connected on one end, is to the block. I connected it to the alternater housing. After putting it all together, I connected the lead coming from the coil to the coil holder. I checked for spark and don't see any coming from the coil wire. I am getting gas. The battery is charged. Disturbing to say the least. Any reasonable ideas or suggestions will be appreciated. The alternators are the same numbers 911 603 120 04. Could I be shorting out somewhere?
