Is anyone seeing how much sand is in this regulator?!?! That's not even half of it!!!! How does that even fit in there?!?! Does this have anything to do with the issue at hand???

So what's the solution?? What can be causing that?? Bad ground? Bad cable? Dirty connections, loose connections. including the ignition switch. I don't have any truck manuals so I can't say, specifically.

ok, lets start the trouble shooting. with the van off positive side of the battery to negative side of the battery reading= with the key in the run position but the engine off
the ballast resistor should have 2 connectors on it. what is the highest voltage reading you get using the battery negative and the ballast as the postive? you can also unplug the vr and check the pin with voltage using the case as ground when it is bolted up to the body, what voltage do you get there?
if either of this is different than your first reading at the battery, you need to start checking a few more things. does the voltage at the vr change if you use the battery ground instead of the case as ground? if not then you have to start chasing the positive side back. the positive passes through the bulkhead connector 3 times. you can bypass this temporarily to see if your problem goes away by running a wire directly from the pos of the battery to the highest voltage side of the ballast resistor. this will back feed the system with battery voltage directly so it isn't passing through the bulkhead.
start the van and check charging again with the bypass installed. if that works, then it is a bad connection in the bulkhead that needs to be cleaned or replaced. you will have to follow the line or check the wiring diagram to see which ones need to be checked. This will work. What I might add is if you determine the problem is at the bulk head connector, clean all the wire connectors, not just the wires to the charging system. If those connections are dirty and making poor contact, so are the rest of the connections in the bulk head connector. The sand you are seeing in the regulator might be caused by the dust/sand blowing around in the air where then van has been parked.

I tried in the past to pull the wires out of the bulkhead connector to clean them with no success ! Not sure if I just gave up after a few minutes but I may need to make a tool or something because those connections are very solid as far as I remember! I live in Arizona and we don't have that type of sand where I live! It's more of a silty clay not beach sand like the stuff from the vr!!!! I thought that was kinda weird! Maybe it's from when I lived in California? Or most likely from driving the I40??? The majority of the miles on it are from driving either on the 101 in Cali or I40 in Arizona... Whatever the case it was an interesting find and surprised if the vr is still working properly, which I'm still not sure of! I wouldn't be surprised if more than one thing is wrong with it though! Last time something happened the driveshaft fell off at the diff and the distributor broke at the exact same time! Anyway, I'll get out there and perform those tests and brb! That "sand" is the filler inside the unit. You might think your connections are clean, the voltage checks say otherwise.
