Will you kindly collect from my office two dynamos taken from Chassis 64-HC and 92-HC. respectively. The particulars are as follows:- a/- 64-HC. The car came into Cricklewood a little over a week ago, with a burnt-out dynamo. The wiring was examined, and Cricklewood say that nothing could be found the matter with it. The car has come into the Works since then, with a dynamo again burned out. The only thing Mr.Strong in the Repair Dept. could find, himself, was a loose terminal connection. In both cases the burn-out was most thorough, so far as the dynamo was concerned. We have impressed upon Cricklewood, on more than one occasion, the need to examine the whole wiring system and make certain that all the terminals are tight, and further, that they check the output on the dynamo as a second safe-guard. b/- 92-HC. This is a very similar case, the dynamo being returned from Messrs Watson & Company, Liverpool. There is a thorough burn-out of the dynamo itself, but we have no information to say that any terminals were found to be loose. We have pointed out to Hm.{Capt. W. Hallam - Head Repairs} that he must take up with Watsons at once, the question of checking the whole of the dynamo connections. In view of the foregoing, I propose that you should examine both of these dynamos with the object of giving an opinion as to whether the burn-out is due to:- 1. A loose connection, in all cases, a point which Cricklewood are contesting. 2. If an owner were to run his car at say 30 to 40 miles an hour, when he would be getting approximately maximum output from his dynamo, and keeping his battery continuously on charge, would such conditions result in a "burn-out".
