Hey y’all, I acquired all the parts to make the Duraspark conversion on my 1986 F-150, so I removed the EEC and used the duraspark system. When it came time to crank the engine after static timing it, I realized I had no spark from the coil. I first confirmed I had 12 volts in both start and run, which I did, I measured 540 ohms across the distributor pickup which is normal, continuity through the distributor body, continuity and correct resistance through both coil windings, continuity through all wires on the Duraspark harness, voltage from the “i” terminal on the starter, and voltage through the ballast resistor. I then manually switched the coil primary and got spark on the secondary. Still no spark when I crank over the engine. Read somewhere that the module must be grounded to bare metal, but have seen clean ground back through the black wire on the distributor body to the module. Since everything has checked out, I assumed the module must be faulty (being a Cheap Duralast). I just replaced the module and the coil. Why might I not be getting spark as I should have the first time. And yes, I’ve gone through all the wiring and I have voltage where I should on the correct connections. Any thoughts? Thanks

Hey y’all, after taking some suggestions last time to go with a duraspark system on my 1986 F-150, I acquired all the parts to make the conversion. When it came time to crank the engine after static timing it, I realized I had no spark from the coil. I first confirmed I had 12 volts in both start and run, which I did, I measured 540 ohms across the distributor pickup which is normal, continuity through the distributor body, continuity and correct resistance through both coil windings, continuity through all wires on the Duraspark harness, voltage from the “i” terminal on the starter, and voltage through the ballast resistor.

Read somewhere that the module must be grounded to bare metal, but have seen clean ground back through the black wire on the distributor body to the module. Since everything has checked out, I assumed the module must be faulty (being a Cheap Duralast). I just got back from autozone and about to swap in the new module. Why might I not be getting spark as I should have the first time. And yes, I’ve gone through all the wiring and I have voltage where I should on the correct connections. Thanks
