The American Farmworks 50‑B Electric Fencer is an AC‑powered livestock containment unit that delivers a high‑voltage pulse across the fence line via its internal energizer and relay circuitry. Common failure points for this class of fencers include power supply degradation (transformer or rectifier), relay contact wear, capacitor leakage, and insulation breakdown on the output leads; these often manifest as intermittent or no shock delivery. First‑check diagnostics: verify 120 V AC input voltage and continuity to the energizer terminals, inspect the relay contacts for pitting or corrosion, and examine the output capacitors for bulging or electrolyte leakage before proceeding with component replacement.[oss-gpt-20b]
