| X8782 To PN.{Mr Northey} from EFC. c. CWB. Hs.{Lord Ernest Hives - Chair} Ey. EFCl/T7.6.26. RE PHANTOM IGNITION. X8780 x8680 Answering your PN{Mr Northey}6/DN4.6.26, we have a comparatively simple type of oil excluding device which can be fitted at not very great expense to a customer's ignition to eliminate probably almost completely this oil trouble. I have arranged with EY. that we would be prepared to make this change to Mr. Sidney's car under an A.T.D. number. We do not, at the moment, desire this to be widely known, as the matter in its wider aspect is at the moment under discussion with BJ. In my previous memo. EFCl/Tl.6.26, perhaps I did not make it quite clear that I was referring more particularly to chassis batteries in which the necessary separation introduces a higher resistance (both true and back E.M.F.) than in stationary storage batteries, so that the high voltage figures do not necessarily apply to those other types of batteries. I think however that you probably understood this. As regards the side lamps, I think it is already the case that lamps which are made more particularly for chassis work and labelled 12/14 volts are actually what we should call 15 volts in an ordinary way. At any rate, so far as I can make out there does not seem to be more than a little trouble due to this cause which, after all, must be Contd. | ||
