Inspection

Inspect Alternator Rotor Assembly

 

1. Visual inspection
Check the condition of the slip ring.
HINT:
The slip ring and brushes are in constant contact to allow the generated current to flow to the rectifier.
Any arcing at this contact will eventualy damage this contact point.
Any damage will interfere with the electric current and prevent the alternator from operating properly
 
2. Cleaning
Using a cloth and soft bristle brush, clean the slip ring and rotor. If the slip ring is burnt or scored (unservisable), replace the rotor assembly.
