As the seasons change, it’s the perfect time to give your generator a little TLC after its summer rest. Just like us, generators need a quick check-up to ensure they’re ready to perform when you need them most. A simple pre-season health check can help prevent unexpected failures, extend the lifespan of your generator, and give you peace of mind knowing your backup power is reliable.

Pre-Season Generator Maintenance Checklist

To help you avoid any surprises, we recommend running through this essential checklist before the season kicks in:

1. Battery Check

• Ensure the battery is fully charged (12-13V).
• If voltage drops below 9V during cranking, replace the battery.
• Keep the battery connected to a trickle charger for reliable auto-start functionality.
• Inspect connections for any signs of wear or animal damage.

2. Engine Oil

• Check the oil level using the dipstick and top up if necessary.
• Use the correct oil type:
  • Diesel generators: 15W-40 diesel oil.
  • Petrol generators (e.g., Westinghouse): 10W-40 petrol oil.
• Change oil every 200 hours of operation.

3. Coolant Check

• Ensure coolant is filled to the radiator neck.
• The coolant should be bright green. If brown or rusty, flush and replace.
• For liquid-cooled generators, inspect fan belts for tightness and cracks. Replace if necessary.

4. Fuel System Inspection

• Check fuel levels and condition. If fuel is older than six months, drain and replace it or add a stabilizer (e.g., Fuel Doctor).
• Inspect for fuel leaks and ensure the fuel pump is primed.
• Consider replacing the fuel filter every 400 hours of operation.

5. Auto Start Mode Configuration

• Verify your generator is in auto-start mode.
• Check settings on the Victron touchscreen, Colour Control, or Cerbo.
• Ensure the generator and Cerbo are properly connected via Relay 1 terminal.

6. Test Run

• Start the generator and check for smooth operation.
• Standard RPM guidelines:
  • Air-cooled generators: ~3000 RPM
  • Water-cooled generators: ~1500 RPM

Pro Tip: Keep track of the hours on your generator and schedule maintenance every 200 hours.

Generator Troubleshooting Guide

Looking for more troubleshooting tips? Check out our detailed Generator Troubleshooting Guide for additional insights and fixes.

Even with proper maintenance, generators can develop issues over time. Here are some common problems and their solutions:

1. Generator Won’t Start

For Air-Cooled 5.7kVA Models:

• Check the fuel stop lever: Ensure it’s positioned correctly to the right and securely latched.
• Inspect for airlocks: If the generator struggles to start, loosen the nut at the fuel injector and try again. Look for air bubbles to clear.
• Test the battery: Even a fully charged battery can have a dropped cell, which can prevent the generator from starting under load.

For Water-Cooled 9-62kVA Models:

• Ensure the fuel stop lever activates the fuel pump lever. If there’s no movement, inspect the operation cable.
• Check for airlocks or water contamination in the fuel. Loosen the nut at the fuel filter housing and manually pump the primer until a steady fuel stream appears.
• Starter motor issues: If the starter motor isn’t engaging, the solenoid might be jammed. A gentle tap can free it. If it still doesn’t engage, check for full power to the starter motor.

2. Poor Performance During Operation

• If your generator is running rough or cutting out, check for old fuel, clogged filters, or faulty spark plugs (for petrol models).
• Inspect the coolant levels and ensure the radiator is not clogged.
• Run the generator for 1-2 hours to confirm everything operates smoothly.

Additional Preventative Maintenance Tips

• Check the air filter regularly and clean or replace it as needed.
• Ensure proper generator housing: Keep it on a concrete slab with an eave for protection from the elements.
• Configure periodic test runs: Set up the generator to automatically start every two weeks to circulate fluids and maintain reliability.
• Verify VRM state-of-charge settings: Ensure settings are within 20-60% for battery-powered auto-start configurations.

Final Reminders

• Regular servicing is key! Oil and fuel degrade over time, even if the generator isn’t used frequently.
• Keep a log of run hours and schedule maintenance every 200 hours.
• Always use fresh fuel and the correct oil to prevent unnecessary wear and tear.
