This troubleshooting guide can be an aid for the serviceman to find the cause of existing problems. Several common problems are covered in the guide, but these problems are not arranged in any particular sequence.Identify your particular type of problem from the Problem Index, then go directly to that problem in the guide. However, when you begin the procedure for that problem, start at Step 1 and follow through the step by step procedure. The steps that follow in a particular problem provide a definite sequence to be followed for a logical, one by one elimination of many variables. These steps are arranged in order from the more probable/easiest to check, to the less probable/more complex to check.Whenever the cause of the problem is found and corrected, stop the test (as shown by stop signs). Do not continue through the complete procedure just because it is there.
