Powerspark Electronic Ignition explained in more detail:

The kit uses a simple magnetic trigger and optimises dwell to provide a reliable and consistent spark across the rev range. It is easy to install and maintenance free.

Each kit comprises a baseplate with electronic module, trigger ring and all wiring. The new electronic baseplate mounts exactly where the points and condenser baseplate sat. The kit connects directly to the coil using the wires provided, red to the positive side and black to the negative side. The ignition kit will automatically shut down if the ignition is left switched on without the engine running to prevent component damage.

Powerspark Electronic Ignition Kits are designed to work with a coil resistance above 1.5 ohms, typically 3.0 ohms. Some performance coils operate at a lower resistance and will need the High Energy electronic ignition kit.

Full fitting instructions are included with your kit, and plenty more instructions can be found on our blog
