Onan P4500i Overload LED Service Prep

Use this when a Cummins Onan P4500i overload LED or output complaint needs owner-safe notes before service.

Owner-safe checklist

• Operate portable generators outdoors only and away from openings; record model, serial number, load, LED state, and runtime.
• Disconnect loads and shut the generator down if the overload LED repeats, output is unstable, or exhaust conditions are unsafe.
• Use qualified generator service for repeated overload, output, engine, or fuel-system faults.
