[crossed out] X 3560 [/crossed out] When we finally come to the vibrator regulator control it would not be so necessary to have three contacts, because the dynamo voltage will only stay at normal when the charging switch is off, but it would still be desirable, and we would rather see it done, to use the three contacts and disconnect the field circuit. 2. X.1413 We had arranged on the scheme submitted to you that the relay current for operating the main switch in the box had to pass through the ignition switch on the steering column in such a manner that unless the ignition switch were on, the relay current could not flow. This was particularly asked for by one of our Paris Representatives, but I note that this is not arranged for on Lec.1089. EFC. {E. Fowler Clarke - Electrical Engineer} | ||
