1988 Ford Ranger 4x4 wiring/voltage issue.

Well we discovered the culprit. The harness going into the alternator had an exposed wire on one end and when I went to take it off from the other end the gray plug just crumbled apart and now one of the three wire push-ins broke off in the female end. I will have to do some sort of splicing to get it back to at the very least working condition. These damn northeast winters can wreak havoc on plastic parts. At least we figured out the issue. Thanks for all your help!!
