This reproduction coil is the replacement for the original Lucas 3ET, as used on the early unit-construction Triumph and BSA competition models with the Energy Transfer ignition. This listing is for (1) coil.

The single-output coil can be used in a 6 or 12 volt application, with CDI or points ignition systems. The mounting points are 32mm on centers. Sourced from Wassell and manufactured using modern technologies.

The coils receive current directly from the alternator and provide the spark to the contact breaker points without rectification. Ignition timing and the integrity of the condensers are critical to the proper operation of this battery-less ignition.

In the Energy Transfer, or “A.C. Magneto” ignition, the coil requires a direct ground from the steel-laminated body to the motorcycle’s frame. (2) coils are required for use in the ET ignition system, so a bracket may need to be fabricated to properly mount and ground both coils. For best results, refer to the factory workshop manual when fitting the coils and servicing the ignition.

Please note: Due the nature of the product, we unfortunately do not accept returns on bearings, service tools or electrical components. Please be confident about your purchase before ordering. If you have questions, please contact us.
