| To BJ. from Hs.{Lord Ernest Hives - Chair} x5840 Hs{Lord Ernest Hives - Chair}8/LG7.12.25. 10,000 MILES TEST ON 9-G-111. x5840 x5240 x5205 BJ2/H1.12.25. We have experiments in hand to try and improve the relief valve unit so that it will be less likely to be affected by dirt. We are also trying improved means of filtering the oil. With reference to the short circuit of the Klaxon wire in the steering column. We are expecting shortly to standardise a single wire on the steering column instead of two. This will enable us to use a much better insulation. This follows the practice which has been adopted on the Phantom Klaxon Switch. Hs.{Lord Ernest Hives - Chair} | ||
