| WST X6142 S/W. Hs{Lord Ernest Hives - Chair}/Wst...from PN.{Mr Northey} Copy to Bg. 58-GN. PN.{Mr Northey}2/WT9.12.32. I was disappointed in not finding the output of the dynamo on this car capable of dealing with the lighting load, although it included two headlamps of 60 watts each. Is it not the case with this vibrator system of control you are justified in making use of a larger output from the dynamo having regard to the fact that there is never any risk of overheating the machine from having to charge a battery, the voltage? of which has risen very considerable due to charging.
