Elements and Performance Criteria
- Assess starting motor operation
- Magnetism, induced voltage and electromagnetism and electric motor principles are understood.
- Starting motor component functions and multi-pole/winding/shunt wiring arrangements are understood.
- Cranking motor drive mechanism is correctly performance tested.
- Starter locked armature current, voltage and torque are correctly determined.
- Test and rectify starting motors
- Starting motors are dismantled and assembled according to manufacturers' recommendations.
- Testing is performed to determine shorts to ground, turn shorts, winding continuity, etc.
- Solenoid, relays and over-temperature devices are correctly tested.
- Starter engagement mechanism is tested and adjusted where possible i.e.: pinion clearance.
- Starting system is free of excessive voltage drops.
- Starting and charging circuit connections are correctly made, tightened and insulated.
- Starter locked armature current, voltage and torque are correctly determined.
