At 75% WGDC then you should see around 9v between both solenoid wires. The factory side will be 12v and the JB4 side 3v.

I learned long ago trying to help people diagnose electrical issues with their single turbo solenoid setups is a loosing cause. You need a good mechanic on site to diagnose and fix if something has been shorted, melted, fuse blown, etc, in the factory harness.

I second what Terry said.. Its not always cut and dry.. You need someone that is good to tackle the job for you if you don't feel that you can.
