I was using my 9000 kbs Warn winch on a 78 chevy 4x4 to pull up shrubs today
and my alternator didn't have the juice to run it. it would drain the
battery and i'd have to wait for it to build up enough power to run it. All
the auto parts places i've called says the 78 350 uses a 63 amp alternator,
but i can't find any thing that puts out more power? Anybody know what i
can do to get enough just to run it without having to go to some dual
First off, A Dual Battery Setup is not expensive to add to a 73 to 87
C/K Truck (Deisel factory parts from a junk yard). Second Dual Batteries
with a Electric winch help keep the winch supplied with enough "juice"
that it does not put a sevre load on the charging system.
As for Alternators, you can run a Later Model TBI R/V Chassis 105 Amp.
Bolts in place, changew the fan and pulley to yours.Alternators work
the same no matter directionof rotaion.
I just checked the advance auto parts web site
for a 78 K pickup 350 engine and they show
tto alternators that are 100AMP or more.
You can order one of these through their web site, if
you don't have a local store.
