Wired an Aston Martin V12 with an EMU pro 16. It’s from a DB7 so the Ford era of AM, so it’s using Motorcraft 3 pin ignition coils.
Looking at the wiring diagram for them, I thought there were active coils. However that didn’t work on the car, tried them as passive coils and they fired. Well 10 of them did. Apparently Ford added an extra ground pin to a passive 2 pin coil.
Pro16 uses H bridge 4A+B as the ignition 11 and 12 outputs. I tested all the coils and wiring to confirm non of that was the issue.
Can ign 11 and 12 be used with passive coils?
I also can’t test ign 11 and 12 on the ignition part of the output test, I can on the H bridge output but that would trigger the coil. Using the assigned ignition outputs mode also didn’t trigger then or get caught by a multimeter.
Testing with a multimeter I get 0.87 Mohm’s to ground when not triggered or in test, 8.7 ohms when testing the output. I think i’d need a oscilloscope to see the trigger pulse, but didn’t have one with me and the multimeter didn’t see it.
