Q:will bad voltage regulator make coil go bad
A:Good question Ben, I will be happy to help. Not usually, fuses are there to prevent spikes in the voltage from damaging vital components. The most common reasons of coil failure are when the spark plugs are neglected: Neglecting to replace worn spark plugs can cause an ignition coil failure similar to open-circuit spark plug wires.
