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!
