    WE HAVE SPARK! Old EST Module saved the day! Now I have this issue: Any insight before I start digging into this?

    No Spark, feels like I’ve tried everything.

    UPDATE: Spark was achieved on the bench test with the old Ignition Module, new cap/rotor/etc and new coil/spark plug wire. I have a tee time I have to get to but after I am done on the course I will be retiming the motor and reinstalling the distributor and coil and hoping for spark.

    After messing around with the wiring and undoing some electrical tape and such I know have a reading a 1.3 ohms from main cable to primary side of coil which is still a little high I believe.

    Crossposted* From the main battery cable to the Purple wire just before entering the coil I have a 29.4 Kiloohm resistance reading... Also I have a steady 10v reading while cranking on that purple wire when everything is hooked up normally. When directly jumped to the battery I only get an 11v...

    Just cleaned every single connection in the ignition system from battery-starter-starter solenoid-coil-distributor Also replaced the battery terminals with fresh ones and cut the ends off the wires to get a fresh connection. No luck on getting spark. Why does it feel like its probably...

    Praying this gives you some insight into helping me find a solution. While cranking the 12-14v drops down to 10v and 5v. Going back and forth on a consistent interval between 10v and 5v. Can take a video if necessary.

    here is some photos, ignore the dirt, its been uncovered for awhile as I've been trying to fix it. (The coil isn't mounted yet btw) New Coil, New Distributor, New EST-Coil Harness, New Plugs. No spark at coil or distributor, I have voltage going through from the purple wire all the way into...

    So even though I have 12 volts going to everything in the system you think I should go through and check all the connections and grounds and make sure they are all good?
