Alternator drives

[Fiero11]

Can an alternator be run CCWise as well as CWise? If yes, do electrical changes need to be made? What changes? Are there any electrical or mechanical problems to consider?

Yes they can be run backwards. Put Lock-Tite on the nut if you do.

The problem with running them backwards is the fan is not set up for reverse rotation and will need to be changed with one that is, expensive to do.

Ahh yes good point. I dont know this for sur but I though some Chrysler engines rotated counter clockwise. Maybe a fan from one world work. Or go and steal one off a marine engine since a boat with 2 smallblock Mercs in it will usually have 1 as reverse rotation.

Nope all Chryco engines spin forward.

(Most) Honda engines spin in reverse though. But use small ass alternators.

Also the Twin engine boats, not all use a reverse rotation for one engine, and besides, any that have, that I have seen use one alternator to feed both engines.
