If the ignition switch is left on without the engine running, a Powerspark ignition kit automatically prevents the coil circuit from remaining energised, helping to avoid component damage and battery drain." By comparison, a conventional points distributor left with the ignition switched on, and the points closed will continuously draw around 4 amps, overheating the coil and flattening the battery within a few hours. A Powerspark system, however, draws only around 25 milliamps when left on, meaning it could theoretically remain powered for several weeks without flattening the battery, while causing no damage to the coil.
The distributor is fitted with an electronic ignition module and Rotor fitted

Cooper"S" 23D distributor, no vacuum unit
This is NOT THE ORIGINAL LUCAS ITEM as the original company and tooling no longer exist but is a new copy of the 40819 to work better with modern day fuels. It does have an original type baseplate with a post but NOT the 32ounce contact set as per the original 40819 distributor, but as many people may make the improvement to contactless ignition this is the perfect looking copy.
See 12G2140MSfor Negative earth only electronic type.
All fitted with the better Red rotor arm upgrade.
Fitted all Cooper S models but MK3 "S" were fitted with 41033-23D type--(Note:25d type distributors have a Vac unit.)
The Distributor must be Lubricated Prior to use.
This distributor has more advance curve similar to the 41033 (Mk3 "S") which was better for acceleration and economy.
