ROAD TROUBLES AND THEIR SYMPTOMS

Q. In case of a sudden vehicle stop what should be suspected? A. The general cause of a sudden motor car stop is either failure of the gasoline supply or of the ignition system. If the stop comes without warning, i. e., if the motor suddenly dies down, the first point to look at will be to see if there is any fuel in the gasoline tank and to look over the ignition system for broken wires. With battery ignition systems the breaking of a wire anywhere in the primary circuit will put the ignition system out of commission. With a transformer coil magneto system the failure of a single pri、 mary wire will also produce the same effect. In a true high tension magneto, about the only thing that will cause the motor to stop suddenly will be a premature short circuit of the regular ground wire leading from the magneto to the shut-off switch.

If there seems to be enough gasoline in the tank the trouble is due to either a broken or blocked up feed pipe or the gasoline shut-off pet cock at the tank may have jarred closed. A particle of dirt in the spray nozzle or the filter at the tank being filled entirely with dirt or water will also prevent gasoline reaching the cylinder. Sometimes the screen interposed in the pipe line to keep dirt out of the carburetor becomes clogged with lint or other matter of this nature and prevents the gasoline from flowing.

Q. How can one tell if ignition system is at fault?

A. The simplest method to ascertain if the trouble is due to the ignition system is to take the spark plugs out of the cylinders and keeping them connected up with their respective wires to see if a spark will pass between the points when the plugs are laid on the cylinder head and the motor cranked over. If sparks jump the gap between the points of the plugs the trouble is not due to ignition.
