:ahem: Yes, coils must be grounded.Every circuit (high voltage even more) requires a path to allow the electrical potentials to balance. Otherwise, the electron shortage created by the secondary coil when firing will seek a path through the air, your hand, back through the primary wiring, etc. The coils on older cars would zap you if the mounting bracket became corroded enough to prevent potential balancing. :shock: This may not be stated correctly for all the electrical engineers out there, but I don't have an EE degree.
