I forgot to disconnect the battery while installing the alternator and it sparked, now my volt gage is not where it should be. Isn't there a resistor or capacitor or diode i may have blown?

Did it spark against the alt, or spark on the engine/frame?

If it hit the case it could have fried a diode.

There is a fusible link at the power distribution block right under C500. Remember that this also is live all the time! The fusible link that runs into the engine harness is the suspected one.

Take a test light and see if you have power at the power distribution post. You should. Check again at the output terminal of the alternator (engine off). If you had power at the posts but not at the alternator the fusible link is out.

If you can get a volt meter, check the out put at the alt, see if your getting 13-14 volts. If you are it's ok, if you only get 11-12 you fried the alt.

You can check at the battery terminals while running and it shoud be 14.3 volts.

As it turns out, I had bent the contacts while trying to connect. So the spark I experienced appears to have not done any damage. The bad part is after replacing the belt with an OEM one, it still slips. I have to rev it to get my volt gage where it should be. I know I should install a belt tensioner but I'm just trying to fix these small annoyances so I can sale it good working condition.
