| X7741a PN.{Mr Northey}5/WT19.4.29. S/W. EFC...from PN.{Mr Northey} Copy to EFC With further reference to my PN.{Mr Northey}3/WT25.3.29. and your reply I shall be glad to know whether you have heard anything further from E.{Mr Elliott - Chief Engineer} in reply to your letter to him on this matter, because we wish to establish as early as possible the practice for coachbuilders to follow as to the point in our circuit system for tapping in such a device as a cigar lighter taking heavy current. I do not consider that this current should be passed through the ammeter, for although no harm may arise from this, at the same time there is no good in it, and many owners might feel, quite justly, nervous as to what was happening. I shall be glad to have your remarks please. PN.{Mr Northey} | ||
