Primary/Secondary Ignition Testing Problems in the secondary ignition system are indicated by high or low spark kV or burn kV and long or short burn time.
SECONDARY IGNITION TESTING 1. Hook up the supplied secondary ignition tester to the coil wire of the 5.0L or any plug wire on the 8.1L. Ensure there is a good ground for the alligator clip and that there is a minimum of ½ inch clearance between the inductive pickup of the tool and all other plug or coil wires. 2. Set the rotary switch on the kV tester to the Spark kV position. The left side of the screen reads the active reading in the wire. The right side of the screen shows the recorded minimum and maximum readings. To reset the readings turn the rotary knob to Off and then back to the desired function. 3. Test each plug wire and the coil wire and record your readings below. Max _______ Cyl.# 1 _______
