| 4. This assumes that a suitable charging apparatus is available which provides a direct current at correct voltage. The charging current must not be allowed to exceed the figure given for normal charging in the table at the commencement of these instructions. The holes in the charging socket are dissimilar diameters in order to prevent reversal, and they are also clearly marked positive and negative, but in addition to these precautions a careful check should be made to ensure that the positive pin of the plug is connected to the positive lead of the charging source, and likewise the negative pin of the plug to the negative lead of the charging source. If the starter becomes sluggish it is an indication that the battery is either reaching a discharged condition or that a fault is developing in one or more of the cells. If a recharge fails to rectify this condition, the battery should be examined by a battery service agent or depot. GENERAL MAINTENANCE. The battery must be well secured in its box so that it cannot move. // The cable terminals should be well coated with pure vaseline (not grease) before putting the battery into service. // The top of the battery should always be kept clean, and as far as possible dry: attention should be given immediately to the least sign of corrosion occurring on the terminals. // Keep the terminals and connectors well vaselined, all contact surfaces clean and firmly screwed up, but do not use abrasives for cleaning, i.e.g. file, emery paper, sand paper. // Do not inspect the battery with | ||
