Safety First: Power Down Risks Before You Troubleshoot

Before you touch a cord or panel, protect yourself and your equipment.

1. Switch off the main breaker on the generator. If you have a standby system, also switch your automatic transfer switch (ATS) to utility.
2. Disconnect all loads. Unplug extension cords and switch off any subpanels or inlet connections.
3. Let the generator cool and wear insulated gloves and eye protection.
4. Never backfeed a home through a dryer outlet. It is illegal, voids insurance, and can injure utility crews.

Two useful facts to keep in mind as you start:

• Many KOHLER standby models can start and stabilize in about 10 seconds and use PowerBoost technology to handle large loads. If your KOHLER starts normally but you read zero volts, focus on the power section, not the engine.
• Tri-State provides 24/7 emergency generator service and weekly diagnostic checks. If you prefer a pro assessment at any step, we can dispatch a certified tech day or night.

Step 1: Check the Generator Circuit Breaker and GFCI Outlets

A tripped breaker is the number one reason a generator runs but shows no power at the receptacles or transfer switch.

• Locate the generator’s output breaker. Firmly push it fully to OFF, then back to ON. Do not just tap it.
• Test built-in GFCI outlets. Press RESET on each receptacle. If the GFCI will not reset with no load connected, the outlet or downstream wiring may be faulty.
• Try a simple test load. Plug in a known good lamp or drill. If it now works, reconnect other loads one at a time to find a bad cord or tool.

If your standby unit feeds an ATS, verify the ATS is not in a fault or service bypass mode. Many ATS panels have status lights that indicate utility, generator, or fault states. Consult your manual for the correct light pattern.

Step 2: Verify Voltage With a Meter

If breakers and outlets look good, measure voltage.

• Use a multimeter rated for 120 or 240 volts AC. With the generator running and its breaker on, measure across hot and neutral at a receptacle. Expected readings are about 120 volts on a 120 outlet and about 240 volts across the two hots on a 240 receptacle.
• Zero or very low voltage suggests loss of excitation, a failed automatic voltage regulator (AVR), or a rotor or stator issue.
• Normal voltage but tripping under load points to an overloaded circuit, a shorted cord, or a ground fault.

On standby systems, view the ATS or controller readout for generator voltage and frequency. If the controller shows normal voltage and frequency but your home is dark, the issue is likely at the ATS or downstream panel.

Step 3: Restore Residual Magnetism (Field Flash) If Needed

Portable and some older standby units can lose residual magnetism after long storage or a heavy short circuit. Without magnetism, the alternator cannot build power.

You can often restore it safely with one of these methods. Only proceed if you are comfortable and the manual permits it.

• Plug-in field flash: Use a corded drill set to forward. With the drill trigger pressed, spin the chuck by hand while the generator runs. The brief backfeed can restore magnetism.
• Battery-assisted flash: Some models allow a brief, controlled application of 12 volts to the rotor brushes. Follow the service manual exactly.

If you are unsure, schedule a professional field flash. Our technicians perform this in minutes and confirm proper output to protect your appliances.

Step 4: Inspect the AVR, Brushes, and Connections

AVR and brush problems commonly cause no-output or low-output symptoms.

• AVR: Look for burned spots, loose connectors, and failed capacitors. Many AVRs are simple to replace and cost far less than a new generator.
• Brushes and slip rings: Worn brushes or dirty rings break the excitation circuit. Replace brushes that are short, chipped, or stuck. Lightly polish dirty slip rings.
• Wiring harness: Reseat quick-connect plugs at the stator, AVR, and control board. Vibration can loosen them.

For KOHLER and Generac standby units, OEM parts are preferred to maintain warranty coverage. Tri-State stocks common AVRs and brush sets for rapid repairs.

Step 5: Rule Out Load and Transfer Switch Problems

Sometimes the generator is fine. The issue is a downstream device.

• Cords and inlets: Replace suspect cords. Check inlet lugs for tight, clean connections. Burn marks are a red flag.
• Manual transfer interlocks: Confirm the interlock plate moves freely and the generator breaker is not mechanically blocked.
• Automatic transfer switches: Verify utility and generator sensing lines are connected. Look for tripped control fuses and verify the neutral bonding arrangement matches your system design.

If the generator makes power at its lugs but your home does not receive it, the ATS contacts or controller may be at fault. Our factory-trained techs can test coil voltage, contact resistance, and controller logic to isolate the failure.

Step 6: Frequency and Engine Speed Checks

Power quality depends on stable engine speed.

• Measure frequency. A stable 60 Hz indicates correct speed. If it is far off, check the governor, throttle linkage, clogged air filter, or fuel issues.
• Surging or hunting under load can trip GFCIs and sensitive electronics. Correct the engine issue first, then retest output.

Standby systems often self-test weekly. If your controller log shows irregular test results, schedule maintenance. Tri-State performs weekly diagnostic checks and offers remote monitoring on select plans so issues are found before a storm.

Step 7: Common Standby Generator Scenarios

Here are quick fixes for the most frequent no-power complaints we see on whole-home systems.

• Utility restored but no transfer back: The ATS may be stuck in generator position. Manually return to utility per the manual and call for service.
• Generator runs, home is dark: Check the generator output breaker and the ATS service disconnect. Confirm the ATS is not in a timed transition delay.
• GFCI outlets dead after rain: Moisture ingress can trip or damage receptacles. Dry the enclosure and replace any failed GFCI.
• After a heavy load start, power dropped: On KOHLER units, PowerBoost helps large appliances start without browning out other loads. If lights still dim or power drops, the load may exceed capacity or the AVR may be weak.

When to Stop and Call a Pro

DIY checks have limits. Stop and contact a professional if you notice any of the following.

• Burned insulation smell, melted connectors, or arcing sounds
• Output stays at zero after breaker resets and basic tests
• Repeated GFCI trips with no loads connected
• ATS fault codes, utility backfeed concerns, or unclear wiring

Tri-State backs installations with strong generator and workmanship warranties. We install Generac and KOHLER units, complete many turnkey jobs in 1 day, and provide 24/7 emergency service across our coverage area.

Prevent the Next No-Power Event: Pro Maintenance That Works

Prevention is faster and cheaper than a blackout repair. Here is what pays off.

1. Scheduled maintenance by factory-trained technicians. Oil, filters, spark plugs, valve checks, and firmware updates at manufacturer intervals.
2. Weekly diagnostic checks. Standby controllers run self-tests that catch many issues early. We verify logs and address alerts before storms.
3. Remote monitoring. Our promotions often include the first year free. You get alerts for faults, low battery, or missed tests.
4. Annual load test. Verifies the generator and ATS handle real demand without voltage drop.
5. Fuel system inspection. For natural gas or propane, confirm correct pressure, regulator function, and leak-free connections.

The result is confidence when you need it. Our A+ BBB rating and high review scores reflect a focus on reliability, not just installation day.

Upgrade Options If Your Unit Is Aging Out

If your generator is over a decade old, parts are scarce, or you have repeated no-output failures, an upgrade may be smarter.

• Capacity right-sizing. We install Generac and KOHLER models from 12 kW up to 80 kW. Homes with dual HVAC, sump pumps, and well pumps often benefit from 20 to 26 kW.
• Quieter, tougher enclosures. New KOHLER units use commercial-grade engines that run quietly and resist harsh weather. Custom colors are available.
• Faster start and better surge handling. KOHLER starts in about 10 seconds. PowerBoost helps start big loads without dimming lights.
• Smart monitoring. Remote alerts, weekly diagnostics, and service plans reduce surprises.

Ask for a free site evaluation. We size the unit, plan the gas or propane tie-in, and provide a firm quote, often the same day.

Quick Troubleshooting Checklist

Use this short list to work from simple to complex.

1. Reset the generator output breaker to OFF, then ON.
2. Press RESET on any GFCI outlets.
3. Test with a simple load like a lamp.

Frequently Asked Questions

Why is my generator running but not producing power?

A tripped output breaker, a failed AVR, or loss of residual magnetism are common causes. Reset the breaker, test a simple load, and check voltage with a meter. Call a pro if output stays at zero.

Will a bad AVR stop a generator from making power?

Yes. The AVR controls field excitation. If it fails, voltage may drop to zero or fluctuate under load. Replacement is usually straightforward and restores normal output.

Can a generator lose magnetism in storage?

Yes. Long storage or a heavy short can erase residual magnetism. A safe field flash can restore it. If you are not sure how, schedule professional service.

How do I check my automatic transfer switch?

Confirm the generator breaker is on, then verify ATS status lights and control fuses. If the generator shows normal voltage but the home is dark, the ATS may need service.

When should I replace an older standby generator?

Consider replacement if repairs are frequent, parts are scarce, or your power needs outgrew the unit. Many homes upgrade to 20–26 kW for modern loads and better surge handling.
