Okay, trying again. Found out how the transistor properly functions. I have ground, 12v and a white ground that generates 54mv pulsing trigger signal from the ecu. Numbers on both sides of the transistor are good . Still no spark. Distributor and related ignition parts have all been checked.
What am I missing and any others ways to check, jumpers for exam
Thanks
Any help would be greatly appreciated.. Usually don't get many replies in electric.
