I just opened my PICO advance 4 channel kit and confused which lead wires to use to check the coil of a Saturn 2.2 L with a PO300. I did a test light on the ignition module and feed is okay as well as the two negative pins. I want to test now the coil module as an ohm test is no guarantee. Thank you.
hi there,you question is a little vague,anyways if your wanting to test your ignition system then first check signal/primary with an attenuator AND NORMAL TEST LEAD if the signal is ok,check power and grounds to the coil,if that's ok and still no output then coil needs to be thrown in the bin
