(for a 1980 externally regulated 242)

When replacing my alternator, I ran into some problems. Instalation was somewhat straightforward. The ground wire and the negative wires are all in the right places. However, I had some trouble with the positive end, which consists of two parts: the fork, and the bolt-on wire. The bolt on wire is simple as well, and can really only go in one location. However, the fork actually has two possibilities: one labled + and the other B+. Should this make a difference? The two separate teeth look identical otherwise.

Anyway, cleary something is wrong. When I jump-start it, it starts right away and all the dashlights disappear as they are supposed to. However, within roughly two minutes or so, the car stops and the amp light comes on. Now what is exceptionaly peculiar about the situation is that the rest of the dash lights don't illuminate as they did when I first encountered alternator problems (only the amp light stays on), and the amp light stays on regardless of whether the keys are in the ignition or not. It basically stays on until the battery dies. Furthermore, after the car dies within the two minutes, it won't even crank when I try and start it up again.

So, I have no idea what is going on. Help.

Thanks,
