1. Chapters 28 Starting System Fundamentals

3. What we call the starting system is really the cranking system

4. There are 2 types of starters
Direct drive, or 1:1
~ 250 rpm
Gear reduction, 2:1-4:1
~ 200 rpm

5. The parts of the starter

6. The Cranking Process
An electromagnet pulls the plunger into the solenoid, engaging the starter’s pinion gear with the flywheel’s ring gear
Current travels to the armature through the brushes and commutator
An electromagnetic field created in the armature core windings causes the armature to spin
Field coils are used to strengthen the magnetic field
The overrunning clutch disengages the starter from the engine once it has started

8. Solenoids can be part of the starter or remote

12. Voltage drop test Engine must be cranking during test

13. Volt/Amp Tester Testing Battery Voltage

14. Testing Starter Draw

15. Why do we hit the starter when the engine won’t crank?
