System Notes — GENERATORS

The generators group covers the alternator end of a generator set: stator, rotor, exciter, bearings, coupling disc, terminal box and the voltage regulation hardware. It converts engine rotation into electrical output at a held voltage and frequency. Bearing wear and insulation degradation are the two long-term concerns — a bearing that starts to rumble will eventually seize and take the rotor with it, while moisture and heat slowly break down winding insulation. Parts in this group are replaced when vibration rises, when insulation resistance falls on a megger test, or when output voltage becomes unstable under load.

System Notes — ELECTRICAL AND STARTING SYSTEM

The electrical and starting system covers the battery, starter motor, alternator, wiring harness, relays, switches and the instrument panel. It carries current from the batteries to the starter to crank the engine, and from the alternator back to keep the batteries charged. Because these machines work in dust, vibration and wide temperature swings, connectors corrode, harness insulation chafes against the frame, and starter solenoids burn out from repeated short cranks. Parts in this group are usually replaced on a symptom basis — slow cranking, a dash warning, lights that dim under load, or a no-start condition traced to an open circuit.
