ProMariner ProTech 1240 Battery Charger
 |
ProMariner ProTech 1240 is a 40‑amp, 12‑V fully automatic marine battery charger with three independent banks and true four‑stage charging for flooded/AGM or GEL cells. Common failure points include the internal rectifier bridge, MOSFET driver ICs, and the charge‑control microcontroller; these components often exhibit overheating or shorted outputs under heavy load. First‑check diagnostics: verify AC input voltage and polarity to the charger’s inlet, inspect the output terminals for corrosion or loose connections, and review any error codes displayed on the unit’s LCD (e.g., “BATT FAIL” or “OVER‑TEMP”).[oss-gpt-20b] |
