1987 chevy truck with carbed Lt1 alternator wiring
I got the motor and everythiung in the truck except I dont know how to hookup the alternator into the old wiring. I have the 3 wire connector from the donor car hooked to the alternator with a heavy red and 1 brown wire and black. Which ones do I hook to the older wiring?
I think the LT1 altenator has external voltage regulator,traditional alt. have reg. built in(i believe) because i ran into the same problem when i put carbed LT1 in 86 camaro,i custom fabbed some brackets and used older alt. and switched pulleys cause lt1 pulley is wider than regular sb alt pulley.I jope this helps good luck
