THE FORD MANUAL

50 points different from the others, it indicates that the cell is not in good order and the battery should be taken to a skilled service man for attention.

When should water be added to the Battery? Answer No. 135


Add nothing but pure water to the cells and do it often enough to keep the plates covered at all times. The solution (electrolyte) should be maintained at a level with the bottom of the filling tube. Distilled water, melted artificial (but not natural) ice and rain water, if obtained in the open country from a clean slate or shingle-covered roof, are generally satisfactory. All water for battery use should be kept in clean, covered vessels of glass, china, earthenware, rubber or lead. In cold weather add water only immediately before running the engine so that the charging will mix the water and electrolyte, and avoid freezing. If, for any reason, it is necessary to add acid, the battery should be taken to an authorized Service Station.

What care should be given the Filling Plugs and Connections? Answer No. 136


Keep the filling plugs and connections tight and the top of the battery clean. Wiping the battery with a rag moistened with ammonia will counteract the effect of any of the solution which may be on the outside of the battery. A coating of heavy oil or vaseline will protect the connectors from corrosion. Keep the battery firmly secured in position. If clamps are loose, the battery will shift about in the compartment and result in loose connections, broken cells and other trouble. If repairs are necessary or if the car is to be laid up for the winter, take the battery to a skilled service man for proper attention and storage. Do not entrust the battery to inexperienced or unskilled hands.
