Power Source PC 75 Repair Service

Professional diagnostic and board-level repair service for this Power Source PC 75.

Power Source PC 75 is a 12‑volt DC battery charger / power supply rated at 75 amps (≈1 kW) commonly used in marine and RV auxiliary systems. Common failures include input over‑voltage or frequency mismatch causing the internal regulator to shut down, output voltage sag below 10 V due to worn capacitors or a failed charge controller IC, blown main fuses, and corrosion on the output terminals leading to poor battery charging. First‑check diagnostics: verify line voltage (100–130 VAC) and frequency against spec; measure the 12 V DC output under load for proper voltage and current; inspect all fuses, relays, and terminal connections for signs of damage or corrosion; review any error codes or indicator LEDs on the unit.
