I'm doing a TPI swap and I have some problems here. I don't have any spark when I turn the engine over. I used a different coil than previously. I had an internal coil, and now I have an external coil. I ran a hot wire from the pink on the coil directly to the battery just to see if would fire and it didn't. I tried a similar coil with the same results. Where is a good place to start tracking down the problem? Do I have to wire it differently? Could it be the module inside the distributor? I know that I may not have the correct ESC. I have the one from the carb motor. Thanks for your help.

Using a test light or meter, is there power (12 volts) at the end of the pink lead? Should there be a red lead vice pink from the ignition source?

Coils are simple, as you know. Take a points ignition coil, ground one of the primary terminals, apply battery voltage to the other terminal, pull off one of the two primary wires and a spark should come out the secondary terminal.

Module inside the dist saturates the coil and a spark should be generated. Go over your connections and or substitute back to original or to where you had spark and continue from there. Modules and pick-up coils do go bad.

I would use the distributor from the TPI set-up since its ECM controlled.

Thanks Everett, we have spark now!
