I give up. I don't have an ohm meter, so I can give you the resistance of any one sensor, or part of the harness but here's my problem/s...
First and most important the vehicle.... 1991 Jeep Cherokee 4.0L/AW4/NP231
New parts into this.... Rebuilt engine, ALL new sensors, new alternator, new ECU, new engine harness, all of my grounds have been cleaned throughout the whole truck. That's why it makes this really hard to troubleshoot (at least for me)
The problem... I'm overcharging quite a bit. It spikes to almost 19 volts at random, also a new thing is it randomly dies out now without warning. new CEL is set off either so I have no idea, I put another new alternator and another new ECU in it just in case that it was faulty from the factory, but my problem was still there.
