Is there an easy multi-meter test you can do to see if the alternator has crapped out? I guess the fact that my battery doesn't charge is proof enough, but I just wanna make sure.

Nope, if the bulb is burned out the alternator will not excite and will not charge.
Jim, that's wrong. If the bulb is burned out the alternator will do NOTHING. The electricity created by the alternator does not run through the bulb. Once the alternator is excited, you can take the bulb out and it will keep on charging. But the alternator needs that little kick start to start making power. There's a ton of articles about alternators on the web if you want a clearer understanding. |
