| X6070 E.{Mr Elliott - Chief Engineer} From Hs{Lord Ernest Hives - Chair}/Wst. Hs{Lord Ernest Hives - Chair}/Wst.2/MA.28.12.32. NEW R.R. SWITCH-BOX. X6069 We hope on the new switchbox you are designing, that all circuits including body lights and accessories will be off when the switch is in the "off" position as the main idea of this scheme we were hoping would be complete protection of the battery against discharge due to negligence in switching off lamps and accessories, etc., when leaving the car. On Pensport, Peregrine and Japan where battery ignition is solely relied upon this feature will be important. We are also mentioning this feature in a note we are sending to By/RD. as a result, of an examination of wiring diagram D.Sch.625. Hs{Lord Ernest Hives - Chair}/Wst. | ||
