I would replace the alternator and the voltage regulator to be sure, but sounds like the Alternator is charging on the halves.

My 1991.5 did this and it was the alternator charging only on 180 degrees of a revolution.

 

this is the second alternator first replacement was a reman second one was brand new still ticking
dont have a clue

 

I dunno then, if the alternator checks out good.

 

Run a wire straight off one of the regulator bolts to the negative on the battery make sure it has a really good ground. Also get the good regulator from Dodge they last a lot longer.

 

ill give that a shot but sounds like kind of a jimmie rig but hey if it works it works ill let u guys know

 

Make sure the alternator is good, still sounds like it is only half charging.

 

Actually a lot of people do it.

 

I did it too actually.

 

ok ran a wire from the voltage regulator to the neg. on the battery nothin changed dont know what to do any more
