Mr. Alternator high output alternator
Well I got my high output alternator and tried to put it on Saturday. After ripping everything apart, mounting it and putting the whole car back together, it squealed like a beatch! That is of coruse because the Mr. alternator had a 5-rib pulley instead of our 7-rib, and the 5-rib was significantly smaller.
DOH!
I replaced the stock alternator and went on my way.
Now I called them today and they said to simply throw the old pulley onto the new alternator.
Couple of questions:
1) How can I check the output of the alternator? It looks EXACTLY like the stock one and since I'll reuse the stock pulley, I want to make sure I'm not getting taken.
2) What does overdriving the alternator do?

1.) Look at the internals. The high output will have more/thicker windings.
2.) Over speeding it will simply wear the brushes/bearings quicker. The bigger wheel will actually SLOW it down.
I had three 200A altenators on my rolling "boom box" ('88 MX-6 with 24 15's and 9000 watts) that used Ford's standard casing. It's all in the guts.

Coldie,
What model alternator did you buy? I got the 200 AMP last week and haven't had time to slap it in yet. I will check my pulley to see if they sent the correct one. Did you leave the stock wire from the alternator to the starter relay or did you upgrade to a 4 gauge or 2 gauge wire?

Coldie,
Installed my new alternator tonight had to swap pulleys the stock pulley is larger diameter than the one that came with the new Mr Alt. I also had to take off the cable extender from the stock unit and bolt it on the new unit so the stock main cable would hook up at the top of the alternator. Other than that it was a good fit and the power to the accessories seems to have improved quit a bit.
