Todd Engieering Sales PC40B Repair Service

Professional diagnostic and board-level repair service for this Todd Engieering Sales PC40B.

The Todd Engineering PC40B is a 12‑V battery charger that accepts 90–130 VAC and delivers up to 40 A DC output, commonly used in RVs, trailers, or heavy‑duty mobile applications. Common failure points include the input transformer winding, bridge rectifier diodes, internal voltage regulator IC, and the cooling fan or heat sink—any of these can cause loss of output current or overheating. First‑check diagnostics: verify 120 VAC input with a multimeter, measure the DC output voltage and current under load, inspect fuses and thermal protection contacts, and look for obvious signs of burnt components or excessive heat on the board.
