| Mr. Burton, Springfield, Mass. -2- One method of doing this in the two rate charge scheme is to have a small value resistance which normally is inserted in the field circuit but which is short-circuited at the same time as any of the running lamps are switched on. A simple diagram of the arrangement is attached. As you observe, this scheme commences with N.2. series including the L.H. chassis of that series. Trusting this is the information you require. Yours faithfully, FOR ROLLS-ROYCE LIMITED. | ||
