3. BATTERY CABLES AND WIRING IGNITION SWITCH NEUTRAL SAFETY SWITCH STARTER RELAY/SOLENOID STARTER MOTOR

4. TROUBLESHOOTING Problems fall into Four categories –No Crank –Slow Crank –Starter spins but does not engage –Excessive noise

5. PROCEDURES VERIFY PROBLEM DEVELOP CONSISTENT METHOD PERFORM VISUAL INSPECTION CHECK BATTERY PERFORMANCE VERIFY ENGINE CONDITION IF NO CRANK OR SLOW CRANK (BE CAUTIOUS!)

6. TROUBLE CHARTS FIND NORMAL AMPERAGE STARTER DRAW SPECS. BY SYMPTOM, CAN SOMETIMES DIAGNOSE PROBLEM IN STARTING SYSTEM TESTING EQUIPMENT MUST BE ACCURATE

7. QUICK TEST TURN HEADLIGHTS ON CRANK ENGINE NOTE RESULTS DON’T OVERCRANK ENGINE

8. CURRENT DRAW TEST DISABLE IGNITION VISUAL INSPECT HOOK UP EQUIPMENT TURN OFF ALL ELECTRICAL LOADS PERFORM TEST

9. CURRENT DRAW TEST VOLTAGE SHOULD NOT GO BELOW 10 VOLTS AMPERAGE SHOULD BE ABOUT 4 CYL. 125-150 6 CYL. 140-160 8 CYL. 160-200 small block 8 CYL. 200-240 large block

10. CURRENT DRAW TEST

11. VOLTAGE DROP TEST A CIRCUIT RESISTANCE TEST IS ALSO CALLED A VOLTAGE DROP TEST YOU HAVE TO TEST BOTH THE POSITIVE AND THE NEGATIVE SIDES

12. VOLTAGE DROP TEST INSULATED CIRCUIT VOLTMETER ON LOW SCALE HOOK UP EQUIPMENT CRANK ENGINE NOTE VOLTAGE LESS THAN 0.5 VOLT ALSO CALLED A INSULATED CIRCUIT RESISTANCE TEST

13. VOLTAGE DROP INSULATED CIRCUIT LAB 164

14. VOLTAGE DROP GROUND CIRCUIT SELECT LOW SCALE HOOK UP EQUIPMENT CRANK ENGINE NOTE RESULTS LESS THAN 0.2V VOLTAGE DROP

15. VOLTAGE DROP GROUND CIRCUIT

16. SOLENOID CIRCUIT TEST DISABLE IGNITION LOW VOLT SCALE CONNECT ACROSS SOLENOID CRANK ENGINE VOLTAGE LESS THAN 0.2 VOLT

17. SOLENOID CIRCUIT TEST

18. FREE SPEED TEST TESTS STARTER FREE LOAD AMPS RPM CAUTION! COMPARE RESULTS TO SPECS

19. Bench testing a starter

20. STARTER R & R DISCONNECT BATTERY! IDENTIFY WIRES PAY ATTENTION TO SHIMS, ETC. ADJUST DRIVE GEAR CLEARANCE RE-CHECK OPERATION

21. THE END
