ELECTRICAL FUSES
A short circuit occurs when any two wires or metal portions of opposite polarity contact at exposed places. Danger attends such a condition. Shortcircuited wires will heat and burn off the insulation very rapidly, and the battery is rapidly exhausted and internally strained. To prevent expensive damage fuses are inserted in vital circuits, their function being to melt and thus break the circuit when the amperage passing through them exceeds a certain pre-delermined value. Alternatively a number of cars are fitted with a vibrating circuit breaker, which cuts in on a dead short or overload and prevents the overheating and other faulty conditions. New circuits should be protected by fuses. Avoid the dangerous practice of substituting blown fuses with copper wire except in strict emergency, and see that the new fuses are not above capacity. Bind all chafed wiring, or, better still, replace it.
