The middle solenoid is the brake and the front one is the 2 speed, not sure about the one at the back. The brake and pressure switches have 2 wires, i disconnected those and plugged them back in. I tapped everything with a spanner and found 2 earth wires on a chassis post that dissapeared into harness near the switch wires so cleaned that too. No luck, I have some diesel comp test gauges here that i may be able to adapt to check charge pressure but wouldnt have a clue where to test the charge pressure. My plan of attack next will be to try figure out if the brake switch is faulty so i will try a continuinity test across the wires when turned off and then somehow try to get a test with it all running which may require a small block under cab and a mate sitting in there at an angle lol.</p></blockquote><p></p>
