Reply To: 1938 Bendix TMD spark issues?

I looked at one of your other posts and noticed that there is only one primary circuit for two coils.  Interesting, I’ve never seen that on any other motors.  So if both coils are seeing the same primary voltage, then I wold assume that if only one of them sparks, there’s an issue with the other coil.  Have you tried closing down the plug gaps to maybe 0.020″?  Or increasing the capacitance of the condenser?
