Job Locations and Reviews
Performed annual maintenance on a 120kW diesel liquid-cooled standby generator. Inspected coolant concentration, radiator condition, belts, hoses, battery bank, engine oil, and fuel filters. Replaced both the primary and secondary fuel filters, changed the engine oil and filter, tested all batteries under load, and ran a full facility load transfer test covering the treatment process and emergency lighting circuits. During the inspection found the oil cooler had a weep at one of the plate joints that had not yet progressed to a drip but was showing staining on the mounting bracket beneath it. Documented the oil cooler finding in the service report, discussed repair scheduling with the facilities director, and confirmed the generator was cleared for continued operation pending the cooler repair appointment.
Completed annual service on a 15kW air-cooled standby generator at a residential property in Madison. Inspected the battery, oil level, spark plugs, air filter, enclosure, and overall generator condition. Changed the oil and filter and replaced the spark plugs due to normal service wear. Found the air intake rain cap cracked from exposure and replaced it to prevent water and debris from entering the intake. Tested the generator through a full startup and simulated power outage, confirming proper operation and reliable performance.
Responded to a homeowner whose 18kW air-cooled generator had not run a complete exercise cycle in several weeks and was showing a fault light on the control panel. Pulled the diagnostic history and found a recurring fuel system fault that was causing the engine to start but not sustain fuel delivery past the initial prime. Inspected the fuel solenoid valve and found it was sticking in the partially open position, drawing enough fuel to start but not enough to sustain idle under the load of a full exercise cycle. Cleaned and tested the solenoid, confirmed it was releasing fully on command, ran multiple startup and exercise cycles to verify consistent fuel delivery and stable idle before clearing the fault and updating the service record.
