Coleman PMP 1200 power inverter

Coleman PMP1200 is a 1200 W (2400 W peak) portable AC‑output inverter that converts 12 V DC battery power into 110 V AC. Common failure points in this class include blown input fuses, degraded rectifier diodes, overheating of the MOSFET bridge, and loss of low‑voltage cutoff or thermal protection circuitry. First‑check diagnostics: verify the battery voltage is within operating range (≈10–14 V), inspect all input/output fuses and the main power switch for continuity, and confirm that the unit’s internal temperature sensor and overload relays are functioning by monitoring the status LEDs or error codes during a short test run.[oss-gpt-20b] Post Comment
