The automatic cut-out is set in the first instance by the makers and should only be touched in exceptional dircumstances. There is an unlikely possibiyility of sparking and consequent pitting at the contacts, causing the cut-outs to fail to break. Such will also the battery to discharge through the dynamo and will be quite evident by the ammeter showing a large unexpected discharge current. In such circumstances pull off charging switch immediately and inspect cut-out contacts. It may be necessary to clean these contact with the aid of some fine glass paper. After doing this, a little vaseline may be placed on the surfaces which make contact. If it be desired to use an inspection lamp, this may be connected to the plug provided withinthe switchbox. We recommend under "Care of Battery" the use of another such plug for the purpose of charging the battery in position on the car from an external source. Contd. | ||
