| -2- EFC1/T30.1.22. Contd. dynamo is not sufficiently high to break down the sulphation, that battery is useless on the car. The only difficulty we see with the vibrator regulator control is in the perfection of the necessary vibrating mechanism. Electrically, the windings can be arranged to suit the requirements of the electrical system under all conditions. The Midgley-Scholey system does not prevent overcharging the battery and therefore cannot be claimed as the only one which properly takes care of the battery under all conditions. They also speak of the constant voltage system as having been thoroughly tried out in America and discarded. This is surely incorrect. The junction box is an interesting departure from the usual practice, but, one would think, of doubtful reliability. EFC. | ||
