Power to ignition coil - can I test with multimeter?
Hi,
I am investigating a no spark issue on my 1984 3.2 Carrera. I have tested to see if there is power going to the coil by putting a multimeter between the positive and negative terminals of the coil with the engine cranking. This reads zero volts, but I have since read somewhere that you can't use a multimeter to test for power to the coil since the power comes as a pulse from the DME, and thus the multimeter will always read zero volts.
Is this true, or does my test indeed show that no power is going to the coil?
Many thanks,
Charles
