New London, IN Standby Generator Installation & Maintenance Tips

Estimated Read Time: 9 minutes

If your generator not producing power has you stressed, take a breath. In many cases, you can restore output with a few safe checks. Below is a fast, step-by-step troubleshooting guide that shows what to try first, what to avoid, and when to call a pro. If you are in Indianapolis, Evansville, or nearby, our 24/7 team can test your system and your automatic transfer switch fast. Limited‑time savings are listed below.

Safety First and Quick Checks

Before touching anything, keep yourself safe.

• Turn off and disconnect sensitive electronics. Surges during testing can damage them.
• If you smell gas or see damaged wiring, stop and call a licensed technician.
• Wear eye protection and gloves. Avoid loose clothing around moving parts.
• For standby units tied to your home, consult your owner’s manual and note any alarms on the controller.

Never bypass safeties or jumper wires. If a step calls for live electrical testing, that is a job for a pro.

How Standby Generators Make Power in 30 Seconds

Understanding the basics helps you troubleshoot faster. A home standby system has four key parts:

1. Engine: Spins the alternator at a set speed.
2. Alternator: Creates AC power. It uses a magnetic field to induce voltage in windings.
3. Voltage regulator: Controls output voltage as loads change.
4. Automatic transfer switch (ATS): Senses utility loss, starts the generator, and switches your home to generator power. When utility returns, it switches back.

Modern KOHLER units can start in about 10 seconds and use PowerBoost to handle large appliances without dropping other loads. Generac systems auto start the moment utility power fails and can run on natural gas or propane, so there is no manual refueling.

“Jason from Tri State did a great job installing our standby generator. We lost power just five days after installation and the generator came on automatically without a hitch.”

Rapid Checklist When the Generator Runs but There Is No Power

If your engine is running but nothing in the house is on, work through these in order.

1) Verify the Load and Cords

• If you are testing with extension cords on a portable unit, try a different cord and outlet on the unit. Use a known-good device like a lamp.
• On a standby system, confirm you are testing house circuits that are actually on the generator panel.

Why this helps: A failed cord, tripped GFCI on the device, or a dead receptacle can mimic a generator failure.

2) Check Generator Breakers and GFCIs

• Many units have a main breaker on the generator itself. Set it firmly to OFF, then back to ON.
• If your unit has GFCI or AFCI receptacles, reset them and retest.

Why this helps: Breakers can trip during startup or when a motor load kicks in.

3) Confirm ATS Position and Utility Status

• Look at the ATS indicator. It should show whether you are on utility or generator.
• If utility power is present and the ATS never switched to generator, you may not see generator output inside the home even if the generator is fine.
• If the ATS is set to manual or has a bypass lever, return it to automatic per the manual.

Why this helps: A transfer switch stuck on utility or left in bypass prevents generator power from reaching the home.

4) Controller and Alarm Reset

• Note any fault codes on the controller. Low oil, overspeed, undervoltage, or sensor faults can block output.
• Clear non-critical alarms by following the manual. Do not clear persistent critical faults without diagnosis.

Why this helps: Controllers protect the system. Clearing a nuisance fault after verifying conditions can restore power.

If There Is Still No Output: Likely Culprits

When basic checks pass but there is still no power, the issue is usually in the alternator, voltage regulation, or transfer path.

Loss of Residual Magnetism

Alternators need a small magnetic field to start making power. Long storage or a heavy overload can bleed this off.

• Symptom: Engine runs smoothly, frequency seems normal, but voltage measures near zero at the outlets or lugs.
• Fix: Field flashing can restore magnetism. This requires the right equipment and procedure to avoid damage. Call a qualified technician.

Voltage Regulator (AVR) Failure

The AVR stabilizes output voltage.

• Symptoms: Wildly fluctuating lights, very low or very high voltage, or zero volts even though the engine speed is stable.
• Checks: Visual inspection for burned components or loose connectors. Confirm correct sensing wires and ground.
• Fix: Replace and recalibrate the AVR. This is a pro task to prevent overvoltage damage to appliances.

Worn Brushes or Rotor/Stator Issues

On brush-type alternators, brushes wear over time.

• Symptoms: Intermittent power, sparks at the slip rings, or output that drops as the unit warms.
• Fix: Inspect and replace brushes, clean slip rings, or test rotor and stator windings. Requires meter tests and training.

Sensor, Harness, or Breaker Faults

• Loose neutral or ground can block proper voltage or trip protection.
• A failed main breaker on the generator can appear as no output.
• Damaged harness connectors from heat or vibration can interrupt the excitation circuit.

When the Transfer Switch Is the Issue

Your generator can be perfect while the home is still dark if the ATS is not transferring.

What to look for:

• Status lights: Most ATS units display source availability for utility and generator.
• Mechanical interlock: Only one source can be connected at a time. A jammed mechanism prevents transfer.
• Control signal: The ATS needs a start/transfer signal from the generator controller.
• Service disconnects: Some ATS installations have separate disconnects. Verify they are on.

What to avoid:

• Never force the switch handle.
• Do not remove covers while energized. Arc flash risk is real.

Professional testing includes source simulation, contact resistance checks, and controller firmware review. Our team installs and services automatic transfer switches that detect outages, start the generator, and shut it down when utility returns. We can verify both sides of the system in one visit.

Maintenance Steps That Prevent No‑Power Events

Most no-output calls are preventable with routine care.

• Weekly self-test: Many systems run an automatic self-test. Tri-State’s home generators feature weekly diagnostic checks. We also offer weekly systems checks where we perform a full diagnostic review so your system is ready for the next outage.
• First-year remote monitoring: Eligible installs include free remote monitoring and maintenance for the first year. That lets us spot low battery voltage, missed exercise cycles, and fault codes before an outage.
• Fuel supply: Natural gas or propane lines should be sized correctly. Low gas pressure under load can stall voltage production.
• Battery health: Replace batteries on schedule. Low cranking speed can cause undervoltage faults.
• Keep it clean and dry: Rodents, dust, and moisture can corrode connectors and windings.
• Professional service: Factory-trained technicians should test voltage and frequency under load, inspect the AVR and brushes, check fluid levels, and update firmware on the controller.

Local tip: In the Midwest, summer thunderstorms and winter ice can hit in the same year. Schedule maintenance in late spring, then again before peak winter to stay ready in Indianapolis, Fort Wayne, and Evansville.

When to Repair vs. Replace

A solid, well-maintained generator can run for thousands of hours. Still, there are times when replacement is smarter.

Consider replacement when:

1. The alternator has severe winding damage and parts are scarce.
2. The AVR, rotor, and brush set all need replacement on an older unit.
3. You have frequent outages and the current size cannot support your essential loads.
4. Repair costs approach a significant share of a new unit with warranty and remote monitoring.

Replacement advantages:

• KOHLER units start in about 10 seconds and use PowerBoost to start large appliances without dropping other loads.
• Generac and KOHLER models offer fuel flexibility with natural gas or propane. No manual refueling.
• New installs often include strong warranties on both the generator and our workmanship.
• Turnkey installation can be completed in 1 day in many homes, minimizing downtime.

Financing is available to ease upfront cost, and regional promotions can trim your project price.

Frequently Asked Questions

Why is my generator running but not producing electricity?

Common causes include a tripped main breaker, ATS stuck on utility, failed AVR, worn brushes, or loss of residual magnetism. Start with safe resets, then call a pro for regulator and alternator checks.

Can I fix loss of residual magnetism myself?

No. Field flashing requires specific tools and procedures. Incorrect steps can damage the alternator or create unsafe voltage. Have a certified technician restore the field safely.

How do I know if my automatic transfer switch failed?

Look for status lights that show utility available but no transfer, or a handle that will not move under approved conditions. A technician can test the control signal and contacts safely.

Will a KOHLER or Generac generator power big appliances?

Yes. KOHLER units start in about 10 seconds and use PowerBoost to start large loads. Generac and KOHLER models support natural gas or propane for reliable, automatic operation.

How often should my standby generator be serviced?

Have a factory-trained technician perform maintenance at least annually, plus a pre-season check in severe weather regions. Weekly diagnostic checks and first-year remote monitoring help catch issues early.
