The MERCURY Coil Driver is a quality high performance spark generator designed for plain coils without built-in drivers. The Mercury ECU can drive coils with built in drivers directly but you have to use the external Mercury coil driver for basic coils.

This driver comes in 2×2, 4×4 and 6×6 driver configuration. This means each driver has a trigger signal. If you have for example a 4 cylinder with 4 coils you will require the 4×4 driver. The mercury coil driver may be configured for wasted spark or single coil. See the wiring diagrams on these connections.

The Mercury coil drivers use a specialized component that can drive the primary up to 360 Volts creating a 36 Kilo Volt output on most coils. The driver is current limited to 10 Amp and has a soft discharge feature should the ECU not trigger it within a certain time. It has over temperature protection that will prevent overheating of the driver in long charge time duty cycles. It also has an overload LED that comes on at 4 amperes and can be used as an indication to set up charge times. See the charge time section.
