Flow Charts

Always start with the top left box of the chart, except when there is a note above it. A few flow charts will have notes above the top most box of the chart. These notes must be read and followed first. Each box will have instructions to perform a test, a result of a test, or inspections/repairs to perform.

The top left box will normally be a test to perform with two or more possible results in the row of boxes below it. After performing the test as instructed, choose the result box which best matches the result you got. Next, perform the repair or test indicated in the box below the result box chosen. Continue performing tests or inspections until you find a problem. Once you have found a problem, repair it and follow any instructions at the bottom of the chart.

When a problem is found, it is not necessary to complete the inspections or repairs listed in the box. However, it is very important to read and follow any instructions or notes at the bottom of the floe chart page after repairs are complete. Most test boxes will have a circled number to the left of them. This number refers to a note on the facing page. Find the list number the same as the test box for an explanation of the test.
