[] 6Test spark plug leads for continuityCalibrate ohmmeter on low ohms scaleAttach one ohmmeter lead to each spring terminalWhile wiggling both spark plug covers and entire length of the spark plug lead, the resistance should remain near zeroReplace spark plug lead if your test results varyTests Using Ignition Analyzer INotel When conducting these tests to the coil, do not exceed its maximum specified amperagePower Test
I Note When using Stevens analyzer ST-75 to power test the ignition coil, Stevens load adaptor NoPL-88 or equivalent must be connected between the analyzer's red primary lead and the primary terminal of the coilTest the C.Dignition coil with polarity connections normalConnect the analyzer's red primary lead to the coil's primary terminal Connect the analyzer's black primary lead to the coil's ground tab Connect the analyzer's high tension lead to one of the coil's high tension lead terminals Connect jumper lead between the other high tension terminal and the coil's ground tab steady spark at, or before, maximum specified amperage indicates the coil is goodRefer to Ignition Coil SpecificationsSurface Leakage Test The ignition coil and spark plug lead should be tested for leakage or insulation failures using the ignition analyzerLeakage is caused by moisture, cracks, or holes in the coil housing or spark plug leads
