Ignition Coil Inspection
Measuring arcing distance The most accurate test for determining the condition of the ignition coil is made by measuring arcing distance Remove the ignition coil (see Ignition Coil Removal) Connect the ignition coil [A] (with the spark plug cap left installed on the spark plug lead) to the tester [8], and measure the arcing distanceAuxiliary Wires [C]
A WARNING
To avoid extremely high voltage shocks, do not touch the coil or leadIf the distance reading is less than the specified valuethe ignition coil or spark plug cap is defective Needle Arcing Distance Standard: mm (0.28 in or more
J H080J5BS2
To determine which part is defective, measure the arcing distance again with the spark plug leads removed from the ignition coil (see Ignition Coil Removal )If the arcing distance is subnormal as beforethe trouble is with the ignition coil itselfIf the arcing distance is now normalthe trouble is with the spark plug lead III IC
Measuring coil resistance If the Coil Tester is not availablethe coil can be checked for broken or badly shorted winding with hand testerHowever, hand tester can not detect layer shorts and shorts resulting from insulation breakdown under high voltage Disconnect the primary leads from the coil terminals Measure the primary winding resistance as follows [A] OConnect the tester between the coil terminalsOSet the tester to the rangeand read the tester Measure the secondary winding resistance as follows [8] ORemove the spark plug leads (see Ignition Coil Removal) OConnect the tester between the secondary lead terminalsOSet the tester to the kGand read the tester If the hand tester does not read as specifiedreplace the coilWinding Resistance Standard: Primary windings 1.532.07
