| JLF. From Ha/Wst. c. to GA/EV.{Ivan Evernden - coachwork} c. to Hn.{F. C. Honeyman - Retail orders} *C.P. Ha/Wst./A.21.10.35. BUTLERS STOP LAMPS. We are not sure how these are arranged on customer's chassis but we should be glad if you will ensure that the switch is placed on the negative side of the lamp as per diagram. Positive feed lamp switch earth This will prevent any danger if the switch should fail. The switch on the Green Bentley which failed was incorrectly wired up. Messrs. Butlers representative visited us to-day and we have approved the modification they have carried out. In addition we have asked them to dispense with the insecure moulded finger tight terminal and substitute a nut and lock washer. Ha/Wst, | ||
