(If a IGNITION SYSTEM tachometer is connected to the Tach term ., disconnect it before proceeding with the test). CHECK . Check spark at plug with spark tester J-26792 or equivalent (ST-125) while cranking {if no spark on one wire, check a second wire) A few (REMOTE COIL / SEALED MODULE sparks and then nothing is considered no spark. CONNECTOR DISTRIBUTOR) ALL ENGINES No Spark Spark EXCEPT 2.5L TRUCK . Disconnect 4 term. distributor connector and check for spark. Check fuel, spark plugs, etc. See Section 2 symptoms. TEST LIGHT No spark Spark TO D.C. POWER SUPPLY (1.5 to 8V] . Check for spark at coil wire with tester while cranking. (Leave spark tester connected to coil wire for Steps 3-6). Replace pick-up coil PN No Spark Spark GBRE . Disconnect distributor 2 term. "C/ + " connector. . Ignition switch "on", Engine stopped, Inspect cap for water, cracks, Fig. 1 . Check volts at " + " and "C" term's, of dist. harn, conn. etc. If OK, replace rotor. Both term's. 10 volts or more Both term's. under 10 volts Under 10 volts "C" term. only 4 . Reconnect dist. 2 term. conn . With ign. "ON", check voltage from tach. term. Repair wire from module " + " term. Check for open or gnd. in ckt. to gnd. (term, may be taped back in harness). to "B" term. of black Ign. coil connector or primary ckt. to ign. sw. from "C" term. to ign. coil. If Ckt. is OK, fault is. ign, coil or conn .. Over10 volts Under 1 volt 1 to 10 volts . Connect test light from tach. term. to ground. . Crank engine and observe light. Repair open tach. lead or conn and repeat test #4. Replace module and check for spark from coil as in Step 6. Light on steady Light blinks Spark No Spark 5 Disconnect distributor 4 term, connector. . Remove dist. cap. System Replace ign. coil, OK . Disconnect pick-up coil connector from module. it too is faulty . Connect voltmeter from tach. term, to ground. * Ignition on. . Insulate a test light probe to 1/4" from tip and note voltage, as test light is momentarily connected from a voltage source (1,5 to 8V) to module Replace ignition coil and recheck term, "P". (Fig. 1). for spark with spark tester. If still no spark, re-install original coil and replace dist. module .. Voltage drops No drop in voltage 6 . Check for spark from coil wire with spark tester as test light is removed from module term. Check module ground. If OK, replace module. No Spark Spark · If no module tester (J24642) is available; . If module tester (J24642) . Is rotating pole piece Replace ign. coil and repeat Step 5 is available: test module still magnetized? Yes NO No Spark Spark OK Not OK Check pick-up coil Replace pole Ign. coll removed is OK, Check coil wire Replace conns. Check pick-up piece and reinstall coil and check coil System OK from cap to coil. If module coil (Coil resistance shaft assy. wire from dist. cap. if OK, OK, replace coil. should be 500-1500 replace dist. module. ohms and not grounded).
