Mobile Power That Shows Up When It Counts

Trailered generators are the ultimate “we’ll worry about it later” asset—until a storm knocks out power and later becomes now. Winter adds cold oil, thick fuel, and brittle cords to the usual neglect. A pre‑holiday service pays back the first time your lights stay on while the grid blinks.

Start with a clean tank and fresh fuel. Aged gasoline or untreated diesel causes hard starts and erratic running. Drain or polish old fuel, replace filters, and treat tanks with the appropriate stabilizers. For diesel sets, confirm winter‑grade fuel and keep water separators drained.

Exercise under load. Don’t just “bump start” monthly—perform a timed load test that stabilizes coolant temp and proves the governor, AVR, and breaker performance. Log output voltage and frequency; drift is a red flag you can fix now, not in sleet at midnight.

Battery and cranking system. Load‑test the starting battery, clean terminals, and verify charging circuits. Consider a small maintainer for units that sit for weeks; cold weather drains batteries fast.

Pre‑heat helps. Block or oil pan heaters dramatically improve starts below freezing. Use labeled, heavy‑duty cords and test GFCI outlets now; winter moisture makes nuisance trips more likely.

Cords, connectors, and grounding. Inspect for cracked insulation and corroded lugs. Replace any suspect cords and confirm you have the correct adapters for your site loads. Verify proper grounding and transfer procedures so safety isn’t improvised under pressure.

Airflow and enclosures. Snow can block intakes and exhaust. Stage units where airflow is protected and post a quick‑start placard with choke settings, warm‑up times, and safe load steps.

Reliable mobile power isn’t luck—it’s discipline. Give your generator a real workout in November so December’s storms are just another day at work.
