Ignition Coil h
Measuring arcing distance: The most accurate test for determining the condition of the ignition coif is made by measuring arcing distanceRemov the ignition coilConnec the ignition coil (with the spark plug cap left installed on the spark plug lead) to the tester, and measure the arcing distance
To avoid extremely high voltage shocks,do not touch the coil or lead
lt the distance reading is less than the specified value, the ignition coil or spark plug cap is defective3 Needle Arcing Distance Standard: mrn or more
T determine which part is defective, measure the arcing distance again with the park plug caps removed from the ignition coilTklf the arcing distance is subnormal as before, the trouble is with the ignition coil itselfIfthe arcing distance is now normal, the trouble IS with the spark plug capsMeasuring coil resistance: If the Coil Tester is not available, the coil can be checked for broken or badly shorted windingwith hand testerHowever, hand tester cannot detect (aver shorts and shorts resulting from insulation breakdown under high voltageDisconnec the primary leads from the cod terminalsMeasurprimary winding resistance as follows [A]0 Connect the tester between the coil terminals0 Set the tester to the range, and read the testerMeasur (tie secondary winding resistance as follows [B]0 Remove the plug caps by turning them counterclockwise0 Connect the tester between the spark plug leads, OSet the tester to the kQ, and read the tester the hand tester does not read as specified, replace the coilWinding Resistance Standard: Primary windings 0.18
