I had my alternater tested and showed good . But when i install back on truck it wont charge the battery . 1995 dodge dakota v6 4x4 please help me go the right direction with finding out the problem Thanks

Ever find the cure to this problem?

It could be a screwed plug wire to it. Change the plug out, and pay attention to the wires while doing it. if the wires are all green, then there is your problem. your wires are oxidated and won't conduct anything.. If that's the case, then you're in for a rewiring job.
