Overall condition/appearance of equipment (controls, leaks, loose wires)
Fan belt tension and condition
Fuel filter or sediment bowl
Lubricating oil level and viscosity
Coolant level and anti-freeze mixture
Battery electrolyte level and specific gravity and load test
Battery charging rate (trickle charger).
Day tank pump and level switches if so equipped
Operation of cooling thermostat or louvers
Alternator and regulator
Inspect of cooling system for leaks (pressure test), residue and operation. Check engine block heater.
Inspect and clean generator brush holders and brushes
Clean and inspect exciter
Inspect safety shutdown devices. This includes simulated faults on low oil pressure cut-off, high water temperature cut-off, over speed cut-off and failed start.
Inspect and clean engine/generator set control
Run generator set (under load) to check voltage, check frequency, check instrument system and make adjustments.
Clean and tighten electrical connections, clean crankcase breather, check and tighten mounting bolts and wipe unit clean
