| C O P Y S/W EP.{G. Eric Platford - Chief Quality Engineer} LEC/C/7.4.32. re Side Lamp Bulbs. I understand that several of the trials cars have been having trouble with the side lamp bulbs blowing and this matter has been taken up with Lucas and they consider the trouble is due to over-voltage. I should be glad to have your remarks and also will you kindly let me know the maximum voltage that can be obtained out of the dynamo. J.L.E. Skn. for Mx{John H Maddocks - Chief Proving Officer} or La{L. A. Archer} comments please. Thn. 8.4.32. | ||
