| EFC. from R.{Sir Henry Royce} X9730 RL/M22.9.28. CHARGING SWITCH. Ought there to be a non-inductive resistance across the dynamo field to stop sparking on the switch with a view to avoiding burning of the contacts - i.e. will you make an experimental observation of the sparking of the switch when the charge is stopped at full dynamo load ? This has been brought about by the green light scheme much more frequently than previously. R.{Sir Henry Royce} | ||
