The battery powers your generator’s starting system, so it needs care too. Check the battery terminals for corrosion and make sure connections are tight.
Clean any dirt or corrosion you find with a wire brush. Keep an eye on the battery’s charge level.
If your generator sits unused for a long time, the battery can lose power. Using a battery maintainer or charger keeps it ready.
Replace the battery every 2 to 4 years or when you notice it won’t hold a charge well. A dead battery means your generator won’t start when you need it most.
Fuel System Checkups
Your generator’s fuel system needs regular checks to avoid problems. Look for leaks, cracks, or damage in fuel lines and connections.
Replace any worn or damaged parts right away. If your generator uses gasoline, drain old fuel or add a fuel stabilizer.
Old fuel can gum up the system and cause the engine to stall or not start. For propane or natural gas models, check hoses and fittings for leaks.
You can use a soap-and-water solution to spot bubbles, which show leaks. Keeping fuel clean and fresh helps your generator run smoothly.
Testing Transfer Switches
The transfer switch moves power from the utility to your generator during outages. Testing it ensures this switch works properly when needed.
Run tests by simulating a power outage and checking if the switch transfers electricity without issues. Listen for any unusual noises and look for warning lights or error codes.
If you find problems, call a professional to inspect and fix the switch. A faulty transfer switch can stop power from reaching your home, even if your generator is working fine.
Regular testing keeps your backup power system reliable.
