• Starter Solenoid - Visually inspect starter solenoid for indications of physical damage and loose or cor- • Wiring - Visually inspect wire harnesses for damage. Repair or replace any faulty wiring, as required. Refer TESTING COLD CRANKING TEST For complete starter wiring circuit diagrams, refer to 8, 1. Connect volt-ampere tester to battery terminals (1), (2) and (3). See instructions provided by manufac- 2. Fully engage parking brake. 3. If equipped with manual transmission, place gear- shift selector lever in Neutral position and block 4. Verify that all lamps and accessories are turned off. 5. To prevent a gasoline engine from starting, remove Automatic ShutDown (ASD) relay. To prevent a diesel engine from starting, remove Fuel Pump Relay. These relays are located in Power Distribution Center (PDC). Refer to WARNING: IF EQUIPPED WITH DIESEL ENGINE, ATTEMPT TO START ENGINE A FEW TIMES BEFORE PRO- 6. Rotate and hold ignition switch in Start position. Note cranking voltage and current (amperage) draw readings shown on volt-ampere tester. a. If voltage reads below 9.6 volts, refer to Starter Motor in Diagnosis and Testing. If starter motor is OK, refer to Engine Diagnosis in 9, Engine for further testing of engine. If starter motor is not OK, replace b. If voltage reads above 9.6 volts and current (amperage) draw reads below specifications, refer to Feed Circuit Test in this section. c. If voltage reads 12.5 volts or greater and starter motor does not turn, refer to Control Circuit Testing in this section. d. If voltage reads 12.5 volts or greater and starter motor turns very slowly, refer to Feed Circuit Test in this section. Note: A cold engine will increase starter current (amperage) draw reading, and reduce battery voltage HB STARTING 8F - 41 |
