Frequently Asked Questions​

Generator diagnostics involves testing, inspecting, and analyzing the RV generator to identify starting issues, power output problems, fuel-related faults, or control system errors.
Diagnostics are recommended when the generator won’t start, shuts down unexpectedly, produces unstable power, or when the cause of the issue isn’t immediately clear.
Common signs include hard starting, frequent shutdowns, fluctuating voltage, unusual noises, warning lights, or appliances not running properly on generator power.
Yes. Voltage, frequency, and load performance are tested to ensure the generator produces safe and stable power.
Absolutely. Old fuel, clogged filters, fuel pump issues, or air in the fuel line can all impact generator operation.
Yes. Control systems, safety sensors, and shutdown triggers are evaluated to identify electronic or protection-related faults.
Yes. Load testing and monitored operation help uncover issues that don’t appear during brief run times.
Yes. Transfer switches, wiring connections, and grounding are inspected to ensure proper integration with the RV’s electrical system.
Most diagnostic services are completed within a few hours, depending on generator type and issue complexity.
Yes. Diagnostics help ensure reliable power when shore power isn’t available.
Yes. Proper diagnostics often reveal fixable issues, avoiding costly and unnecessary replacement.
Diagnostics are recommended when performance changes, after long storage, before extended trips, or during routine inspections.
