BATTERYELECTRICAL SYSTEMS Dynamic Testing
NOTE: Be sure the engine crankshaft turns freely before proceedingUse digital multimeter during testsTest battery voltageIs the battery voltage equal to or greater than 12.8 Vdc? YES Disconnect two-pin harness from starter solenoidConnect black multimeter probe to the engine or ground, then the red probe to the red harness wire at solenoidRotate ignition key to the start positionMeter should read battery voltageDoes it? YES Reconnect the solenoid harnessConnect black probe to battery positive terminal and red probe to solenoid end of battery to solenoid cable(B) Page 13.9Turn key to start positionThe reading must be less than.1V DCIs it? YES Connect black tester lead to solenoid end of solenoid to starter cable and red tester lead to starter end of same cable(D) Page 13.9Turn key to start positionThe reading must be less than.1V DCIs it? YES Connect black tester lead to starter frameConnect red tester lead to battery negative (-) terminal(E) Page 13.9Turn key to start positionThe reading should be less than.1V DCIs it? NO Clean ends of engine to battery negative cable or replace cableRemove battery, test andor serviceInstall fully charged shop battery to continue the test and continue with left column With black tester lead on ground, check for voltage at large relay terminal, circuit breaker in and out terminals, and across both sides (red and redwhite) of the ignition switch with switch on startRepair or replace any defective parts
