This is a modern style voltage regulator that is ready to be installed. Made exclusively for British motorcycles by Wassell. Simply install this unit inside your old Lucas voltage regulator case / box. Works with many Triumph, BSA, Norton, Royal Enfield, and many other brands that originally came with a Lucas dynamo / generator (E3L, E3N, etc)
Upon purchase we will include a very detailed instruction manual. This will aide you when installing your new 6V DC regulator. Should you have any additional questions please feel free to contact us at anytime and we will be glad to assist you.
