Hayti, MO Standby Generator Installation & Maintenance Tips

Estimated Read Time: 14 minutes

Power is out and your generator is running but the house stays dark. If your generator is not producing power, use this fast, safe troubleshooting guide to get back online quickly. We will cover quick checks you can do in minutes, then show you when to call a pro. Stick around for local tips, plus limited-time savings for Tri-State standby systems.

Start Here: Safety First

Before touching anything, make the area safe.

1. Turn off or unplug sensitive electronics to prevent surges when power returns.
2. Put the generator in OFF or STANDBY per the manual before opening any access panel.
3. Wear dry gloves and keep footing dry. Water and electricity do not mix.
4. If you smell gas, stop and call your utility or a licensed technician.

Why this matters: restoring power can happen instantly after the fix. You do not want a sudden surge to damage appliances.

“One thing I like most about Tri-State was the install process, especially as it relates to the generators. Complete turn-key... And peace of mind.”

Confirm the Obvious: Is the Generator Actually Running and Making Voltage?

Many no-power cases are simple.

• Fuel supply: Ensure the natural gas valve is open or the LP tank has fuel and the regulator is not iced. For portable units, check fresh fuel.
• Oil level: Low oil shutdown prevents damage. Top up with the correct grade.
• Control panel status: Look for any red or amber alarms and note error codes.
• Breakers on the generator: Standby and portable generators have one or more output breakers. If tripped, switch fully OFF, then back ON.
• GFCI outlets: If using a portable with GFCI receptacles, press RESET on each.
• Frequency and voltage: Many inverter or standby systems display 60 Hz and voltage. If frequency is unstable, shut down and call a pro.

Quick win: a tripped output breaker is the number one reason for no power after a heavy load or short.

“Kevin May serviced my standby generator today. Very professional... We just had 3 1/2 days without power generator ran perfectly.”

Whole-Home Standby: Check the Automatic Transfer Switch (ATS)

If your standby generator runs but your home stays dark, the ATS may not be closing to send power inside.

• Utility vs generator position: Most ATS units have indicators for LINE and GENERATOR. If stuck on LINE while utility is out, the switch did not transfer.
• Manual test: With utility power restored, many ATS panels have a TEST or EXERCISE mode. Initiate a test to confirm transfer both directions.
• Control wiring: Loose low-voltage control wires between the generator and ATS can block signals. Visually inspect for obvious disconnections with power safe.
• Fault codes: Modern KOHLER and Generac systems post ATS or communication codes. Record the code for service.

What to do next: if the ATS never clicks or transfers, stop and call a factory-trained technician. The contacts carry high current. Tri-State installs and services automatic transfer switches that detect outages, start the generator, and return to utility automatically.

“These folks are great! Had two whole house generators installed and both are flawless. Customer support is top notch.”

Portable Generators: Cord, Inlet, and Panel Checks

If you are using a portable generator, power loss is often outside the machine.

• Cord and plug: Overheated or burned blades can lose contact. Replace damaged cords.
• Inlet box: Verify the twist-lock is fully engaged. Quarter-turn connectors must seat fully.
• Interlock or manual transfer: Ensure the main breaker is OFF as required and the generator backfeed breaker is ON per the interlock procedure.
• Load too large: Starting a central AC or well pump can trip the generator breaker. Start big loads one at a time.

Pro tip: Never backfeed through a dryer outlet. It is illegal and dangerous. Use a proper inlet, transfer device, and a licensed electrician.

“The Briggs and Stratton Fortress 20kV is a workhorse. It's kept the lights on through a tornado, wind storms, and ice storms.”

No Output With Engine Running: Loss of Excitation or Stator Issues

When the engine runs but outlets read zero volts, the alternator may have lost residual magnetism or suffered a component fault.

• Field flash recovery: Some portables regain magnetism by briefly applying a small DC source through the brush terminals per the manufacturer. Do not attempt without instructions.
• AVR failure: The automatic voltage regulator can fail after surges. Symptoms include fluctuating or zero voltage. Replace with the correct part.
• Stator or rotor damage: Burn smell or dark varnish indicates a winding failure. This requires professional repair or replacement.

For standby systems, the onboard controller will often post an undervoltage or excitation fault. Tri-State technicians are factory trained to diagnose these faults and carry common parts for Generac and KOHLER units.

“Kevin was timely and very friendly. He looked over the generator and completed all maintenance.”

GFCI and Breaker Tripping Under Load

If you see brief power then darkness, protection devices may be doing their job.

• Moisture: Outdoor cords or inlets with condensation will trip GFCIs. Dry connections and use weather-rated covers.
• Neutral-ground bonding: Portables configured with a bonded neutral can conflict with a transfer device. Ensure correct bonding per code and the transfer equipment.
• Motor inrush: Well pumps, freezers, and HVAC draw 3 to 7 times running amps for a split second. Size the generator correctly or use soft-start kits where appropriate.

KOHLER PowerBoost technology helps start large appliances without dropping power to others. Proper sizing plus modern electronics solves many nuisance trips.

“Both are flawless. Customer support is top notch. Highly recommend.”

Fuel System Checks for Standby Units on Natural Gas or LP

Standby generators connect to your home’s existing fuel supply. If the engine hunts or sags, check supply.

• Gas meter sizing: Undersized meters starve the engine during peak demand. Your installer should calculate BTU load for the meter and piping.
• Regulator freeze: In subfreezing weather, moisture can ice a regulator. Keep the regulator vent clear and up to code height.
• LP tank level: Below 20 percent, some regulators struggle to maintain pressure. Schedule deliveries before storms.
• Sediment traps and filters: Clogged traps restrict flow. Have them inspected during maintenance.

A correct gas line and regulator are part of Tri-State’s one-day turnkey installation, which includes permitting, piping, and code checks.

“Complete turn-key from generator and propane tank placement, gas lines, and all electrical work. They do it all at once.”

Controller Alarms and Self-Test Results

Most modern standby systems run weekly systems checks and post clear alarms.

Common alarms and actions:

1. Low battery: Replace the starting battery every 3 to 4 years. Clean terminals.
2. Overcrank: Could be fuel, ignition, or battery. Verify battery voltage before repeated starts.
3. Undervoltage or frequency: Possible AVR or engine speed control issue. Do not load the unit until resolved.
4. Exercise failed: Indicates the weekly test did not complete. Review fuel supply and recent utility events.

If you have remote monitoring, check the app for status. Tri-State offers 24/365 remote monitoring for the first year on select packages, so help can be proactive.

Load Management and Prioritizing Circuits

Your generator may be fine but overloaded by what you ask of it.

• Identify priority loads: Refrigerator, sump pump, furnace blower, medical devices. Delay ovens and electric dryers.
• Staged starting: Start motors and compressors one at a time and let them stabilize.
• Smart load shedding: Many KOHLER and Generac systems include modules that shed noncritical circuits when the generator nears capacity.

Right-sizing matters. Tri-State provides a free on-site evaluation to match 12 kW to 80 kW solutions to your home, lifestyle, and local weather risks.

“In as little as 10 seconds, your backup generator will have your major appliances and electronics back online.”

Seasonal Realities in the Midwest and Mid-South

Homes in Jonesboro, Paducah, Sikeston, Cape area, and along the Ohio River see tornadoes, ice storms, and summer heat. These conditions stress standby systems.

• Ice storms: Keep snow and ice off louvers. Clear around the unit for airflow.
• Tornado debris: Inspect for blocked vents and damaged wiring after storms.
• Heat waves: High ambient temps reduce power output. Keep vegetation trimmed 3 feet around the cabinet.

Weather-ready equipment with rust-resistant outer casings and commercial-grade engines, like KOHLER, is designed for these conditions and runs quietly with minimal maintenance.

“It’s kept the lights on through a tornado, wind storms, and ice storms.”

Preventive Maintenance That Avoids No-Power Surprises

Simple routines prevent most failures.

• Quarterly visual: Check cabinet seals, critter guards, and clearances.
• Semiannual: Change oil and filters per hours. Test battery and clean terminals.
• Annual professional service: Inspect spark plugs, valve clearance, fuel pressure, and controller firmware. Confirm ATS operation.
• Weekly: Let the automated exercise and diagnostic review run. Investigate any missed test.

Tri-State’s service plans include regular maintenance by factory-trained technicians, 24/7 emergency response, and warranty support on both generator and workmanship.

Frequently Asked Questions

Why is my generator running but not producing power?

The output breaker may be tripped, the AVR failed, or the alternator lost excitation. Reset the breaker, reduce loads, and check for alarms. If voltage stays at zero, call a pro.

How do I know if my automatic transfer switch is the problem?

If the generator runs but lights stay off, and the ATS indicator shows utility instead of generator during an outage, the switch may not be transferring. Do not open the ATS. Call a licensed tech.

Can cold weather cause my standby generator to stop powering the house?

Yes. Regulator freeze, low LP level, and iced vents can cause power loss. Clear snow and ice, maintain LP above 20 percent, and schedule winter maintenance.

How often should a standby generator be serviced?

At least annually or by hours run. Include oil and filter changes, spark plugs, battery test, fuel pressure check, controller updates, and a full ATS transfer test.

What size generator do I need for whole-home backup?

It depends on your essential loads and starting currents. Many homes use 12 to 26 kW. Tri-State provides a free on-site evaluation to size it correctly.
