    Default How to test if Ignition module is faulty ?

    Howdy,

    My 4AGZE has a wolf3d v3 and for the ignition setup its running an M&W ECU2 inductive ignition module and 2x bosch coils. From testing it seems there is no spark. I tested each lead for resistance and on 200k setting got from 6.0-8.0 ohms so i dont think its the leads. Which makes me believe its could be the ignition module.

    How would i go about testing the M&W ECU2 module? Just so i can make sure thats not the issue and rule it out.

    This is what it looks like

    UPDATE:
    Just probed the plug with hte multimeter that attached to the module and its reading 11-12v on both the GND to Tigger #1 and #1 and also when testing from Coil Negative #1 -> Trigger #1 & Coil Negative #2 -> Trigger #2,
    So it seems power is getting sent to the module correctly, i just need to know how to find out the module is functioning
