| -12- FAILURE OF ONE CELL. If the battery voltage, when lighting the head lamps goes prematurely low, it may be due to one cell having become through some minor fault, less good than the others. This is best ascertained by the use of a pocket voltmeter, with which each cell should be tested independently, whilst the head lamps are lighted, and the faulty cell located. Ordinarily it may be expected that all the six cells will work together in much the same condition. Any cell, however, which drops out of line with the others, should be carefully tended and if necessary given separate treatment, it being quite easy, with the bolted up connections, to remove a cell at any time. If the cell is past recovery a new cell may be obtained in its place. It should be understood, however, that the necessity for such replacement is considered most unlikely if proper care be taken of the battery. | ||
