Investigate failed starts and warning messages
A standby generator that misses its exercise cycle, displays a fault or starts without powering the expected circuits needs attention before an emergency. The cause may involve the battery, controls, fuel supply or transfer equipment. Tell us the make, model and displayed fault when you call, so we can discuss service availability and the next step.
- Review fault messages and recent operating history.
- Inspect starting, charging and control components within the service scope.
- Evaluate transfer-system concerns and connections.
- Explain repair options and verify operation as appropriate after service.
Repair now or plan for replacement
Equipment age, condition, parts availability and the cost of the repair all affect the decision. A battery or control issue may be repairable, while repeated major failures can justify discussing a replacement. Michigan storms and winter outages make regular maintenance useful even when the system seems to be working. Keep the area around outdoor equipment clear and follow the manufacturer’s care instructions.
