Ok. I finally had a chance to check this and I am not really sure if I have the right tool to do the job. I have a little Analog Multimeter that has DC settings and AC settings. The AC settings are 10, 50, 250, and 500. I set it at ten and touched the leads to the battery and it pegged out. I set it at 50 and it went to 35. I took the lead off of the passenger side battery that goes to the alternator and re checked it and it went to 30. I am not sure I did anything contructive by checking this because I am not sure the Meter I have will do what I need.
Still confused!

30 is way to much ac voltage. Unhook the alternator and check it again. If you still have doubts go to a reputable garage and ask them to check the charging system for a/c voltage. They should know what you are talking about, if they do not run to a better garage. Ask how much they will charge to do this, I would think $20.00 or less.

ACTUAL CAUSE OF MULTIPLE GOVERNOR SOLINOID FALURES:
Since the early 727s Dodge has had a problem with the rear sprag mounted in the transmission case.
The problem is that it is pressed into the case, not bolted or even knurled.
Under high torque applications it comes loose and drags against the clutch drum next to it.
It wasn't a major problem until the electric solonoids were added.
The rubbing of sprag against the drum creates very fine metal powder so fine it gets past the filter.
This powder gets stuck to the magnets in the gov solinoid and jambs it open.
It is possible to use carb cleaner and a battery to clean some of the powder out, but it won't get it all and the solinoid will jamb up again.
The only REAL solution is to replace the rear sprag with a bolt-in unit.
