I bought this 1995 discovery and the alternator was new, but went bad after a couple miles. I replaced the alternator, and it lasted a few hundred miles, then cooked the battery set off the alarm buned up the mass air flow, and melted the front of the fuse box in the engine bay. I am wondering if it is wired wrong. There are 4 posts on the back of the alternator B+,D+,W,S what color wires go where. If someone could look at there alternator, and tell me what wires go where, I would greatly appreciate it.
