voltage is applied to the condenser in the leakage testHandle leads carefully and turn selector switch to "Discharge" before disconnecting leads from condenser after performing this testPOINT TESTING
It is possible to check the electrical condition of the points with the ig-
analyzerConnect test lead to the breaker arm, and connect the second test lead to the breaker assembly screw terminalFigure 4-13Breaker Point Testing
If the points are good, meter reading will in the green area the "Breaker Test" scaleIf reading is in red area, do not immediately
reject the points, but check the test lead connections to make sure that they are tightsecure contact is necessary because of the current used in this testSee Figure 4-13NOTE NEVER FILE to bring reading within the green ("good") areaReject the points if cleaning with trichlorethylene does not give satisfactory readingTESTING Spark plug high tension leads tested for leakage or insulation failures using the ignition analyzer and Connect the to the ignition analyzer as for the testConnect separate test lead with suitable clips to the secondary terminal of the and the conductor of the spark plug lead being testedProbe the entire surface of the lead insulation with the grounded test probeSee Figure 4-14Flashover will apparent wherever the insulation has broken down, due to moisture or carbon
