3.2 Quick reference chart for troubleshooting

It is important to thoroughly under stand each system and the function of all of the parts of terse systems.
A careful study of the engine mechanism will make this possible. When problems arise, it is important to
carefully observe and analyze the indications of trouble in order to save time in determining their cause.
Begin by checking the most easily identifiable causes of difficulty. Where the cause of the difficulty is not
readily apparent, make a thorough examination of the system from the very beginning, proceeding until
the point of trouble can be determined. While experience is an important factor in pinpointing engine
problems, careful study and understanding of the engine mechanism combined with good common
sense will help you to rapidly become more expert at troubleshooting.
