PROBING THE CONNECTOR
When testing the control system from the feedthrough connector with the internal harness connected, contact with
the following pairs of terminals will result in resistance measurements of two solenoids through a shared ground.
The resistance should be twice that of a single solenoid. Refer to Figure 6–34 for solenoid resistance values versus
temperature.
