87 & 91 5.7 TBI Alternator Delima
« on: May 08, 2010, 08:44:22 pm »
I have a 87 C10 5.7 TBI that I just put a 91 3/4 ton 5.7 TBI in and the Alternator Plugs are different. It looks like they both have the same pulley, but my question is do the alternators turn the same direction, or is one a reverse rotation? If someone could help I would be grateful. Both alternators have a serpentine style pulley, not the v-belt pulley style. They have different connector plugs though, so any ideas? Thanks

I'm sure they turn the same way. i would try to keep the 87 on on there so the plug would be easer to mess with

Yeah that's what I was wanting to do cause I'm not comfortable changing wiring. Thanks.
