That's interesting! How did you reroute the wiring around it?

I'm glad you brought up the alternator because that was part two of my question. How do you know the amps of the alternator? The alt I have is a aftermarket one I have no clue what the amp is

They are normally stamped into it somewhere.....however, that does not necessarily mean anything, as they have usually been rebuilt, regurgitated, remanufactured, or whatever, so the stamped rating might not mean a thing.
