Common Questions

Residential Electrical FAQs

Common questions from Triangle homeowners about residential electrical services. Don’t see yours? Call us directly — we’re happy to help.
Why won't my backup generator start automatically during an outage?
The most common causes are a dead battery, faulty automatic transfer switch, or a tripped sensor. We test the battery under load. We verify the ATS is receiving utility loss signals. We check all safety switches including low oil pressure and high temperature cutoffs. Many units also have exerciser timers that fail and prevent startup.
Most diagnostic visits take one to two hours depending on the issue. Simple problems like dead batteries or tripped breakers take minutes. Complex issues like control board failures or fuel system problems require more testing. We carry common parts on our trucks. We can often complete repairs the same day if components are available.
This usually means the automatic transfer switch isn’t closing or the generator’s voltage regulator has failed. We measure output voltage at the generator terminals. We check if the ATS contactor is energizing properly. Sometimes the issue is incorrect frequency. The unit may be in cooldown mode and hasn’t fully transferred yet.
Yes, we service all major brands including Generac, Kohler, Briggs & Stratton, and Cummins. We have access to manufacturer diagnostic software and wiring diagrams for proper troubleshooting. Our technicians attend ongoing training to stay current with new models and control systems. We can work on any residential standby generator.
Code 1500 typically means overcrank or RPM sensor failure. Code 2100 indicates low oil pressure. Code 1501 means overspeed condition. Code 2800 shows a charger problem or weak battery. We use manufacturer scan tools to read codes. We then perform specific tests to verify the actual fault before replacing components or clearing false codes.

We use manufacturer scan tools to read codes. We then perform specific tests to verify the actual fault before replacing components or clearing false codes.
You can safely check the battery connections, circuit breakers, and fuel valve position. You can also review any fault codes on the display panel. However, testing voltage, inspecting the transfer switch, or working inside the generator requires proper tools and training. Incorrect troubleshooting can damage components or create dangerous backfeed conditions.
