CABLE CONNECTIONS
Check the welding cable connections at the weld out- put terminals often. Be sure that the connections are always firm.
BRUSH REMOVAL AND REPLACEMENT
It’s normal for the brushes and slip rings to wear and darken slightly. Inspect the brushes when a generator overhaul is necessary.
