Cranking Test
- Disconnect 2-pin connector (ignition coil primary lead) from distributor to disable ignition system. See Fig 1
. Connect voltmeter and ammeter to battery. See Fig 2
.NOTE: Use commercially available starter tester to perform cranking test. Follow manufacturer's instructions. If starter tester is unavailable, perform test as described in steps 2) through 6).
- Connect tachometer to engine. Turn ignition switch to START position, and crank engine. Check starter cranking voltage and current draw on appropriate meter. See CRANKING TEST SPECIFICATIONS
table.CRANKING TEST SPECIFICATIONS
Application Cranking Voltage Current Draw (Amps) Hitachi 11.0 (1) 60 (1) Cranking speed should be greater than 100 RPM. - If engine does not crank, check battery, battery cables and connections for looseness or corrosion. If engine still does not crank, go to next step.
- Disconnect Black/White wire from starter. Connect jumper wire from positive battery terminal to starter solenoid "S" terminal. Engine should crank. If engine still does not crank, repair or replace starter.
- If engine cranks, check for open in Black/White wire between starter and ignition switch. Check connections for looseness or corrosion. Check ignition switch.
- Check neutral/safety switch and connector on A/T vehicles. Check starter relay, clutch interlock switch and connectors on M/T vehicles. See CLUTCH INTERLOCK SWITCH TEST (M/T) .
