You have to depressurize the system to replace the high side switch.

 

Dang! I knew you would say that. Why did I blow the relay though by jumping the connector? I was about to go back out and make sure I do not have a frayed wire to ground in that circuit. Any thoughts?

 

Okay, i spent some time with my multi-meter and this wiring. Here is what I found:

Ohm check:

Low Pressure Switch - closed
High pressure switch - open
Blue wire from high side to relay - good
white wire from low side to relay - good
black wire from relay to clutch - good
green wire coming into high side plug - do not know where it comes from. it is melted and burned in the plug. there is a green wire to each plug, so I am assuming it is a common wire between them.

So, is the high side switch bad or is there too much pressure in the system? I can tell that I need to replace the plug since it is broken and burned/melted.

I also checked the relay, and the circuit from 30 to 87a (N/C) is good, and 85 to 86 (N/C) is good. 30 to 87 (N/O) is open like it should be. So, is there any other fuse in this circuit that may have caused the clutch to work once when I jumped the high side connector and then not again? Or, is the plug so messed up that it just will not work right (my guess right now)?

Thanks for all of your help.

I already listed the fuses that play a role in this system...
