| *7660 Extract from report of CWH. (France) on 18-EX. 18.12.28. The dynamo gives a very poor output, its maximum charging rate being 6 amps. This is insufficient to maintain the lights for all-night driving. There is not sufficient charge left in the accumulator after an all-night's run to work the starter motor, this meaning when the starter motor switch was pressed, the lamps went down to a dim red. Would you please let us know which way the control brush has to be moved to give us a better output from the dynamo. the dynamo brushes are very noisy at times, this is one of the features which cannot be reproduced when you wish, it comes on erratically. | ||
