Re: Fs ignitions
The biggest reason for the Petronix is adaptive dwell, the hall effect impulse is modulated to provide consistent coil soak.
Many model A owners don't realize the ground path Ford used to complete the circuit was through the engine pans. Once removed, chassis grounding becomes dependent on connections not designed for it, like the drive shaft trunnion and front engine mount. Running a dedicated ground strap to the transmission provides the path needed, without it the petronix will burn..the rest of your electrical system will last longer and function better as well.
