1930 Lucas Dynamo Lighting Set Running Instructions

A brief 23 page booklet on how to maintain the 4 and 6v charging/lighting set on your 1930 motorcycle. The E3 and E25 charging units were not high output units compared to modern charging units but were a major step ahead from the gas acetylene units that were still in use on a lot of older machines. Regulation of the charging system for the battery was a combination of the 3 brush generator and the charge resistors in the headlight, as well as the generator cutout hidden under the end cover of the generator.
