Generator Noise Test

Generator noise may be caused by the following conditions:
^ A loose drive belt
^ Loose mounting bolts
^ A loose or poor fitting terminal
^ A faulty component inside the generator

Replace the generator if the drive belt and the mounting bolts are snug and there is still excessive generator noise.

Do not disassemble the generator. Separating the two end frames will damage the slip ring end frame bearing. CS-130D generator is serviceable by complete replacement only.
