2. Secondary Ignition Will need crossfire demo

3. 11/2001VHS Auto2

4. 11/2001VHS Auto3 Points close or transistor turns on... Primary circuit is complete current flows

5. 11/2001VHS Auto4 Magnetic field builds to saturation

6. 11/2001VHS Auto5 Points open or transistor turns off... If using points, condenser absorbs electrons until points get all the way open

7. 11/2001VHS Auto6 Magnetic field collapses from primary winding... High voltage is induced In secondary winding

8. 11/2001VHS Auto7 Yea, we have heard that enough times! Now what does it do?

9. 11/2001VHS Auto8 Secondary ignition Primary ignition’s job was to make the high voltage Secondary ignition’s job is to get the high voltage to push current to the right spark plug at the right time

10. 11/2001VHS Auto9 High voltage pushes Current (less than 10 mA) to spark plug through secondary circuit

11. 11/2001VHS Auto10 Secondary ignition components Coil secondary winding Rotor Distributor cap Spark plug wires including coil wire (high tension wires) Spark plugs

12. Ignition Coil secondary winding Positive Terminal Labeled: “+” “Batt” Negative Terminal Labeled: “-” “Dist” Secondary Winding Connects from – to center of coil Has about 25,000 windings Standard Resistance is 8,500 to 12,000 ohms Can create approximately 30,000 volts (30 KV)

13. 11/2001VHS Auto12 Distributor caps Electronic ignition Point type ignition Can have male Or female terminals May have a vent May have #1 marked

14. 11/2001VHS Auto13 Distributor caps Electronic ignition Point type ignition May have a vent Ridges are to increase insulation

15. 11/2001VHS Auto14 Inspecting distributor cap Underside Look for cracks Look for worn or missing center carbon button Look for carbon tracks Look for build-up on terminals Look for moisture Outside Look for corrosion on terminals

16. 11/2001VHS Auto15 Carbon tracks (replace cap) Don’t try to clean, will come right back

17. 11/2001VHS Auto16 External corrosion Prevent by using Diaelectric grease

18. 11/2001VHS Auto17 Internal corrosion

19. 11/2001VHS Auto18 Missing carbon button

20. 11/2001VHS Auto19 Arcing cap

21. 11/2001VHS Auto20 Rotors Connect to distributor shaft Can (should) only go on one way Only touches distributor cap carbon button Doesn't touch distributor cap terminals Usually.060” to.100” Some have resistor built in

22. 11/2001VHS Auto21 How rotors should only go on one way

23. 11/2001VHS Auto22

24. 11/2001VHS Auto23 Inspect rotors for: Wearing thru on spring that touches carbon button Signs of spark jumping thru to bottom side Wearing away of tip

25. 11/2001VHS Auto24 Spark jumping thru (hole burned in rotor)

26. 11/2001VHS Auto25 Burnt off spring

27. 11/2001VHS Auto26 Plug & Coil wires (high tension wires) Come with Different amounts of insulation 7mm (point type) 8mm, 8.5mm, 10mm (electronic and computerized ignition) Different kinds of cores Carbon string (up to 7000 ohms per foot) Spiral wound (up to 1000 ohms per foot) Wire core (no resistance)

28. 11/2001VHS Auto27 Removing wires Grasp boot and twist and pull Do not pull on wire Can use plug wire removing tool if there is room to get down under

29. 11/2001VHS Auto28 Use factory routing of wires Improper routing and separation can cause pre-ignition and holes in pistons Wire separators

30. 11/2001VHS Auto29 Firing orders that cause problems GM’s & Chrysler

31. 11/2001VHS Auto30 Demonstration of cross fire

33. 11/2001VHS Auto32 Inspect wires for: Resistance Damage to insulation Damaged boots Signs of burning thru insulation Corrosion to terminals Proper routing and separation

34. 11/2001VHS Auto33 Checking wire resistance

35. 11/2001VHS Auto34 Checking boots

36. 11/2001VHS Auto35 Proper routing and separation

37. 11/2001VHS Auto36 Checking wire insulation under load Mist water onto plug wires with spray bottle Load engine or give vacuum leak Look and listen for spark jumping out of wires to common Works best at night

38. 11/2001VHS Auto37 Spark plugs We will do later in a separate presentation

39. 11/2001VHS Auto38 Nissan’s dual coil set-up Dual carbon button Makes contact on dual Level rotor $$$

40. 11/2001VHS Auto39 Secondary ignition review High voltage, low amperage (up to 50,000v,.010a) Requires excellent insulation Parts include Secondary winding in coil Distributor cap Rotor High Tension wires Spark Plugs
