The generator that fails during a real outage almost always passed its weekly exercise test just fine. Exercise cycles keep the engine lubricated and battery charged, but they don't reveal oil degradation, clogged filters, or cooling system problems. Here's what annual maintenance actually covers.
What Annual Generator Service Covers
A proper annual service includes: oil and oil filter change (required regardless of run-time hours — heat cycles degrade oil even in low-use units); air filter inspection and replacement; spark plug inspection; battery voltage and charge system test; and a full load bank test under actual demand.
The load test is the one most often skipped by DIY maintenance — and the most important. It's the test that reveals transfer switch problems, voltage regulation issues, and fuel delivery that works at idle but can't sustain high-load operation.
What You Can Do Between Service Calls
Listen to weekly exercises. A consistent startup sequence and stable idle are what you want. Rough running, excessive smoke, or failure to start in the normal sequence are all signs to call for service before the next annual visit.
Keep the area around the generator clear. Florida winters deposit ice and snow around units — heavy snowfall can restrict airflow and cause the generator to run hot or trigger safety shutdowns. Make clearing the generator part of your post-storm routine.
Don't disable the exercise cycle. It's what keeps oil circulating through seals and gaskets — a generator that sits for months without running is far more prone to hard-starting and seal deterioration.
What Kills Generators Prematurely
Skipping annual service is the leading cause of premature failure. Oil left for two or three years thickens, loses its protective additives, and allows varnish deposits to form.
Ignoring the battery is the second killer. Batteries fail without warning, often during a winter outage when temperatures are below freezing. Replace your generator's starting battery every 3-4 years regardless of symptoms.
Not testing under load is the third. Annual load testing reveals problems in a scheduled maintenance context rather than during an outage when you're counting on the equipment.
