R.{Sir Henry Royce} 32. BODY WIRING. X6082 X77410 Re Cx.{Major Len W. Cox - Advertising Manager}4/KW.29.1.32. we consider an additional very useful feature would be a master switch on the instrument board, similar to the Bentley, whereby all the accessory circuits could be disconnected from the positive supply when leaving the car. We have had a case only this week on 20-KX where an electrical body heating accessory was inadvertently left on thereby discharging the battery. This feature in any case should be an essential feature on J.{Mr Johnson W.M.} 3. where it is proposed to rely solely on Battery ignition in order to prevent exhausted battery trouble.
