Todd Engineering PC40 Power Source Repair Service

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

Todd Engineering PC40 is a 12 V DC battery charger that converts 120 VAC to a 40‑amp output for RV or trailer batteries. Common failures include overheating of the internal rectifier/transformer, tripped over‑current protection, and degradation of the output filter capacitors, which can cause erratic charging or no output at all. Check the AC input voltage and phase balance, verify the output voltage with a multimeter, and inspect for burnt components or blown fuses before proceeding to internal board diagnostics.
