3k Chinese alternator just stopped mid run

<< < (5/5)

Hi Tyssniffen, a couple of possible causes:
1. Brushes have failed/worn out, test for continuity with ohm meter
2. Armature winding has failed, test for continuity between slip rings with ohm meter
3. Field windings have failed, remove +ve & -ve terminals from rectifier and test for continuity with ohm meter.
4. Shut down under load can remove residual magnetism from field, flash field windings with 12 volt battery to restore magnetism.

Let us know what you find.
