I hope this is the right forum for this question. I'm new to the Megajolt world so bear with me as I get up to speed. I want to thank you all in advance for your help with getting me back on the road.
Some background info...
1970 340 ran fine with distributor and MSD6AL
EDIS-8 is new-old stock
Coils and mag pick up are from a 1997 Ford Crown Vic
Trigger wheel is a custom 36-1 design to fit the Mopar crank pulley bolt pattern
After installing the components, and wiring the system over the winter, I tried to start it today and I have no spark. The light on the MJ unit comes on when turning the key to "on". The MJ and EDIS are powered from the same source, and grounded at the same location.
I went through the signal verification protocol and here's a summary...
VR sensor...0 volts in run and 0 volts in crank. Switched the leads on the sensor and got the same result. I have a 0.027" gap between the VR sensor and the trigger wheel.
PIP Signal...11.5 volts in "run" before crank, about 9 volts during crank (should be 5.5V at crank...is this a problem?) Voltages measured between EDIS pin 1 and ground.
SAW signal...11.5 volts in "run" before crank (should be 0...is this possible?...this is likely the source of my problem), about 9 volts during crank (should be less than 0.2v) Voltages measured between EDIS pin 3 and ground.
Tach out...about 9 volts at run (should be 5.5...again, is this a problem?) Voltage measured between MJ tach out and ground.
Diagnosing and debugging electrical issues in real time is challenging at times. Adding forum questions in the mix adds to the challenge. Please let me know if any other information is needed to help diagnose this no spark issue
Thanks again in advance for your help.
