A generator not producing power is stressful, especially in a storm or heat wave. Use this quick, safe checklist to diagnose common issues and get back online fast. We will show you what to check first, what you can fix in minutes, and when to call a pro. If you own a standby system with an automatic transfer switch, we include specific steps for that too.

Safety First: Basic Rules Before You Touch Anything

Working around electricity demands caution. Follow these steps every time:

Turn off connected loads. Unplug appliances and switch off main breakers feeding from the generator.
Let the engine cool. Hot engines can burn skin and ignite fuel vapor.
Wear eye protection and insulated gloves.
Never backfeed a home through a dryer outlet. This is illegal and deadly.
If you smell gas or see damaged wiring, stop and call a licensed technician.

In Springfield, Joplin, and across the Ozarks, outages often follow storms. Debris and moisture add risk. Take an extra minute to inspect the area for standing water before you proceed.

Step 1: Confirm the Obvious Fast Wins

Many no-power calls are solved in minutes. Work through these in order.

Is the generator fully started and at speed? Wait 30 to 60 seconds after start.
Check the generator’s master breaker. Many portables and standbys have an output breaker on the unit. Reset if tripped.
Inspect GFCI receptacles on portable units. Press Reset on any tripped outlet.
Verify cords. Swap to a known-good cord and outlet. Look for crushed or burned ends.
Remove all loads. A shorted appliance can trip protection as soon as power is applied.

If power returns after you remove loads, reconnect items one at a time. The faulty device will trip the breaker again.

Step 2: Portable Generators — Restore Excitation and Output

If the engine runs but outlets are dead, the alternator may have lost residual magnetism or has a control fault.

Try these owner-level checks:

Voltage selector switch. Some portables have 120V-only or 120/240V settings. Set to the correct mode for your cords and loads.
Field flash via drill test. With the engine running, plug in a corded drill and spin the chuck by hand while pressing the drill trigger. If coils are marginal, this can kick-start output. Use caution and keep fingers clear.
Inspect brushes and slip rings. Worn brushes or dirty rings reduce excitation. Replace brushes if they are short, chipped, or sticking. Clean rings with a non-metallic pad.
Check the AVR (automatic voltage regulator). A failed AVR is a common cause of low or no output. Signs include no voltage, flicker, or runaway voltage. AVRs are modular and often owner-replaceable with basic tools.
Inspect fuses in the control panel. Replace any blown control or sensing fuses with the same rating.

Stop here if you see burned windings, a melted connector, or damaged stator wires. That is a job for a factory-trained technician.

Step 3: Standby Generators — Quick Diagnostics for No Power to the Home

Standby systems with an automatic transfer switch behave differently. Use this targeted flow.

Check the status light or remote monitor. Many Generac and KOHLER systems perform weekly systems checks. Look for any active alarms.
Is utility power available? If the grid is live, the transfer switch may have already returned to utility. Test a receptacle on the street side of your meter using a non-contact tester if safe.
Confirm the generator is running at speed. Most KOHLER units can restore power to major appliances in as little as 10 seconds, so delays point to a transfer issue.
Inspect the generator’s output breaker. Reset if it is tripped.
Verify the transfer switch position. Some switches have a manual test or manual override. If safe and permitted, perform a test transfer per the manufacturer instructions.
Check the low-voltage control cable between the generator and the transfer switch. Loose control wiring can prevent transfer.
Open the main panel and inspect branch breakers. A tripped main or key breaker will leave parts of the home dark.

If the generator is running but the home is still dark, do not force the switch. Call a licensed electrician. Transfer switches contain high voltage and require proper PPE.

Step 4: Fuel, Air, and Sensor Checks that Kill Output

Engines that run poorly often cause low voltage or no power under load.

Fuel quality. Old gasoline loses octane and varnishes carburetors. Drain and replace stale fuel. For standbys, confirm natural gas or propane supply and regulator settings. Frozen propane regulators and closed tank valves are frequent culprits during cold snaps.
Air filter and intake. A clogged filter chokes the engine. Replace filters per the manual.
Spark and plugs. Fouled plugs lead to misfires. Replace and set the proper gap.
Low oil shutdown. Many engines cut ignition if oil is low. Top up with the specified viscosity and inspect for leaks.
Battery condition. Weak batteries can start the unit but fail under demand, confusing controls. Clean posts and test cold cranking amps.

After each fix, retest voltage at an outlet or the unit’s lugs per the manual.

Step 5: Electrical Checks with a Multimeter

If you are comfortable using a meter, these tests help pinpoint the fault. If not, skip to the next section and call a pro.

No-load voltage. With the generator stabilized and no loads connected, measure output. You should see about 120V on a single hot to neutral and about 240V hot to hot on 240V units. If zero, suspect AVR, brushes, or rotor.
Frequency. Many meters read Hertz. Healthy engines hold near 60 Hz. Low frequency points to governor or engine issues.
Under-load voltage sag. Plug in a 1500W space heater. If voltage collapses, look at fuel, carburetion, or engine power.
Continuity across stator windings. If open, the winding is damaged.

Only proceed if you can do so safely. Incorrect testing can cause shock or equipment damage.

Step 6: Common Root Causes and Fast Resolutions

Tripped generator breaker or GFCI. Reset and reduce load.
Loss of residual magnetism. Perform a drill flash or professional field flash.
Failed AVR. Replace with the correct part number.
Worn brushes or dirty slip rings. Replace brushes and clean rings.
Wet outlets. Dry thoroughly and use weather covers.
Transfer switch did not engage. Diagnose control wiring, sensing, or the switch mechanism.
Low gas pressure or empty propane tank. Restore supply and verify regulator.

When in doubt, document the alarm codes and snap photos of the panel labels. This helps your technician bring the right parts.

When to Call a Professional Immediately

You smell gas or see damaged wiring.
The transfer switch hums, chatters, or is stuck mid-travel.
Repeated AVR or voltage faults after resets.
Burn marks on the stator, rotor, or connectors.
The generator starts but stops when loads are applied.

Prevent the Next No-Power Event

A few habits will keep your system ready every time.

Exercise schedule. Let the unit run under light load monthly for 15 to 20 minutes. Many KOHLER and Generac models perform automatic weekly systems checks. Verify the log.
Fuel plan. For portables, rotate fuel every 3 months and use stabilizer. For propane, keep tank levels above 30 percent in winter.
Keep it dry. Store portables under a vented cover. For standbys, clear snow and leaves from around the enclosure.
Maintenance calendar. Change oil, filters, and plugs on schedule. Mark dates on a visible tag.
Remote monitoring. Alerts catch low battery or failed tests before an outage.

Tri-State partners with Generac and KOHLER, offers remote control monitors, and provides comprehensive warranties on both the generator and our workmanship. That means less worry and faster recovery when the grid drops.

Standby Systems: Quick Transfer Test You Can Do

Run this short test twice a year, ideally before storm seasons in Springfield and Joplin.

Make sure sensitive electronics are unplugged or on proper surge protection.
Use the generator’s test or exercise function to start the unit.
Trigger a test transfer per your manufacturer instructions or use the switch’s test button if equipped.
Confirm power in key circuits. Check fridge, HVAC fan, and a couple of outlets.
End the test and verify the system re-transfers to utility.

If transfer fails or lights flicker, call for service. Early testing prevents emergency calls during a storm.

Repair or Replace: How to Decide

Sometimes a dead generator is a sign it is time to upgrade.

Age and hours. Over 10 years with heavy use often means rising repair costs.
Parts availability. If the AVR, rotor, or engine parts are discontinued, replacement may be wiser.
Power needs changed. Many families add freezers, home offices, or medical devices.
Noise and fuel. Newer units run quieter and use fuel more efficiently.
