Briggs & Stratton P2200 PowerSmart Series 2200 Watt 111cc Inverter Generator MECH-NO-OUTPUT Error Fix: Engine Runs But No Power Output

Error code MECH-NO-OUTPUT on the Briggs & Stratton P2200 PowerSmart Series 2200 Watt 111cc Inverter Generator means: Engine Runs But No Power Output. The engine runs but the outlets produce no voltage. On inverter generators, the power goes through an inverter module (engine → alternator → rectifier → inverter → outlets). If the green "output" LED is off while the engine runs, the inverter module may have failed. Check and reset the circuit breaker and any overload resets. Unlike conventional generators, inverter generators convert power electronically, so there is no AVR or residual magnetism issue — the inverter board is the critical component. A faulty inverter board must be replaced as a unit. Check all wire connections between the alternator, inverter board, and control panel.
