LESSON 3 Disassemble and check the intake system2.2 Check the generator

1 Check the stator

- Check that there is continuous current between the lead leads If there is no continuous current, it means the wire has been broken and the stator must be replaced

- Continuous current between lead wire and fault

Check if there is continuous current between the commutator and core If so, the rotor is broken and needs to be replaced.

2 Check the rotor

-Continuous current between commutator and fault.

Check if there is continuous current between the commutator and the core.If so, the rotor is grounded needs to be replaced.
