JB4 or Boostbox?

Jb4

If WGDC is at 0% then both sides should be 12v. Only when WGDC goes over 0 should voltage on one side drop. And at 100% one side should drop to 0v.

It's at 75

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.

I checked all the fuses. No Melted wires. Think I could of shorted out the jb4

The JB4 boards are $175 here if you think that is the issue: http://www.burgertuning.com/N54_JB4_upgrades.html
