The ballast protects the coil and the ignition module. If you want to bypass you should replace both of these with units that can withstand the current passing through them at 14V.



Its protecting only the coil. If you check the wiring diagram, the ECU gets full battery voltage from the vehicle harness.

As mentioned earlier, the stock distributor pickup doesn't care as it's a Variable reluctance sensor and is not powered. The magnetic field creates AC voltage as the reluctor passes by the pickup.

I ran an Accel 8140 coil for years with a stock replacement ECU and never had an issue.
