<b>2.2. Check the generator</b>

<b>1. Check the stator</b>

<b>- 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</b>

<b>- Continuous current between lead wire and fault</b>

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

<b>2. Check the rotor</b>

<b>-Continuous current between commutator and fault.</b>

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