X6091 Try to arrange that the Bosch can be used if necessary. Ours should be almost, or exactly, interchangeable. The Bosch has part of our sequence, but not our safety scheme. We ought not to be able to get teazer circuit when the dynamo is charging. This is good for safety, if possible. I will work at this at Le CanadelHenry Royce's French residence and see if we can get safety simpler. On the dynamo is the usual charging switch. This can rest on a contact when not charging so as to give current to the starter button and green lamp when the ignition is switched on. R.{Sir Henry Royce} | ||
