We came up against trouble very early on, when we had perhaps 6 dynamos to test at once. Owing to the heavy charge the battery needed constant attention. I have asked Mr. Watson (my tester) to make a report on this gadget because it has been so useful, and reliable, and has needed no readjusting. Attached is his report, and description. Yours faithfully, E.J.Brock | ||
