Thanks for pointing this out!! The multimeter I've been using is the bigger CEN-TECH and it's definitely not working properly!!! The CEN-TECH is reading almost 3 volts higher than the small red multimeter and the little charging plug!! The red meter and plug are reading the same so I'm inclined to think that those are correct! I also tested a battery in my other vehicle with the CEN-TECH and the little red meter and the CEN-TECH is giving me 15.6v while the cheaper one is giving me 12.75v!!!! The CEN-TECH is definitely not working properly! Crap! I'll be using the other one from now on!!!! I guess I'll have to go back out there and redo all the tests!!!! Btw the little 12volt plug meter is how I discovered the voltage was too high!

The voltage is definitely still too high! The 12v plug and meter show the same voltage! The readings are as follows...

if you need to drive it tomorrow put in the bypass wire like before, your voltages seem good then. wire it up when you leave for work, when you get there disconnect it, then run it again on your way home and disconnect it when you get there. so it is your power wire to the vr not the vr that is the problem. you basically are losing 3 volts at some point, where you have to backtrack the loss to figure out what part or parts are causing the drop. I have never bothered to fix it when I Get that, I just drop in a relay to give the bypass wire a key on thing so it doesn't leave it energized when the car is off. it all depends on the time you have to dig, but that is what I do to get rid of the problem.

I downloaded the 79 Dodge truck file but it doesn't have the bulkhead diagram.... I already have the Haynes manual and I've been using that manual for years! I'm familiar with the diagram in it and it's seams to be an exact match to my van!
