I still maintain the oil pressure problem is just a broken sensor wire to the sensor. But if you do want those gauges I was keeping as spare I've decided to let them go.
If he fiddled with the back axle it suggests he operated the lever by hand, then the vacuum lock pulled it out as it should at 15mph. As the only diff locks I have played with are on the type 85 I'm working on at the moment you need someone to tell you whether vacuum/pressure is required to put in and throw out or part of the procedure involves a spring. I reckon you could be looking at a split pipe that is blowing out under pressure (and therefore not pushing lock in) but sealing under suction (and therefore pulling it out).
Really doesn't sound like a short somewhere to me.
