Want to test your igniter, or ignitor?

Make sure you perform the test correctly

The entire point of the test is to provide the proper two bit coil identification signal while triggering IGt and then look for the correct coil driver to momentarily switch on.


Igniter power transistor - TSRM pg. IG-15

NOTE: 3v test signal connection points
pin 2 for IG2
pin 2&4 for IG1
pin 2&3 for IG3

On the left side I indicate the test point at the 4 pin connector, on wiring harness side, to the coil pack pigtail.
I found those tabs on the coil pack connectors break off very easy.

Igniter bench test

I obviously used a 9v power source, but my results were the same as on the car with 12v.
My 3V source is an old two battery AA flash light. I removed the lens and bulb, soldered some lead wires to + and - connection of reflector assembly. Now I can make all connections and apply/remove test voltage while watching ohmmeter.

Actron also makes a tester that will perform this simple test.
Just make sure all test the connections are made.
