Todd Engineering Sales PC40 Power Supply Repair Service

Professional diagnostic and board-level repair service for this Todd Engineering Sales PC40 Power Supply.

Todd Engineering PC40 is a 12‑volt, 40 A battery charger used in RVs and other mobile power systems. Common failure modes include MOSFET overheating or insulation breakdown (often under the high‑current transistors), fuse tripping due to short circuits, and capacitor degradation that causes voltage ripple. For first‑check diagnostics, verify the input AC supply and output DC voltage with a multimeter; inspect the MOSFET area for burn marks or cracked insulators; and test the main electrolytic capacitors for ESR and leakage before proceeding with component replacement.
