| -14- Contd. the current is switched on. Another method of securing correct direction of current is to use pole-finding paper, but whichever way it is done, be certain that the direction is right. The number of lamps in circuit, or the variable resistance, must be suitably adjusted to allow of the flow of the required charging current, which should not exceed 8 amperes. Charging in the garage from an external source, with the battery in position on the car, is recommended where conditions of running are such that a greater demand is made on the battery than can be replaced by the dynamo. When a suitable direct current supply is available, we recommend in any case that it be made a rule always to leave the battery on charge at a slow rate (½ ampere or less) when the car is in the garage, as such a procedure will assist in keeping the battery in thorough condition. | ||
