| WST X6142 S/W To Hs{Lord Ernest Hives - Chair}/Wst from Sg.{Arthur F. Sidgreaves - MD} re 58-GN-Vibrator Control. Sg{Arthur F. Sidgreaves - MD}3/E13.12.32 In a recent note you asked me to give my views on this after use. At the present time I have nothing very much to add to what PN{Mr Northey} has already written to you. Further time alone will show whether it succeeds in keeping the battery charged under the conditions under which I normally use the car. I should have thought that with the vibrator control we could have got sufficient output from the dynamo without discharge taking place when the head lamps are on. I notice that it only just keeps pace with the output when the centre spot lamp is on. Sg.{Arthur F. Sidgreaves - MD} | ||
