| C.W.Hancock, Esq., Hotel de France, Chateauroux, Indre, FRANCE. From Ha/Wat. Ha/Wat.3/MA.30.5.35. CH2. We are sending you out to day for fitting to 5.B.IV a fan ventilated dynamo. We are very keen on getting a chassis test of this dynamo as soon as possible so that it can be standardized. Could you arrange some kind of extra load in addition to the ordinary lamps to give the dynamo some work to do. What we suggest is an extra 60 watt lamp bulb wired up to the No.5 terminal of the distribution board. This will come on when the H.S & T switch is on and will serve to share the load between the two fuses Nos 4 and 5. The lamp bulb will serve to provide an extra 5 amp load which would be equivalent to a wireless set load. Ha/Wat. | ||
