I have a Jacobs Electronics ignition system in my '73 1.7. Backed it out of the garage and left it idling. Ran in to get my sunglasses and when I came back the engine had stopped. I turned it over and got a few backfires but it would not catch and run. Now I don't have any spark. Engine turns over fine but the LEDs on the Jacobs box are not lit and I can't remember if they were ever on when the car was not running. I have 12v to the unit and the antitheft wire has a good ground.
I have never worked on an electronic ignition system like this. Can someone help me with a troubleshooting procedure? |

I have one of these ignitions in my most recent project. it fires so far. not a lot of useful info on the net that I have been able to find. I am very tempted just to go back to coil and points.
