American Farm Works 57 electric fence controller

The American Farm Works 57 is an AC‑powered low‑impedance electric fence controller used to energize livestock fencing over a limited range. Common failure modes include loss of output due to degraded capacitors or damaged high‑voltage diodes, tripped safety interlocks from faulty ground connections, and power supply issues such as blown fuses or worn transformer windings. First‑check diagnostics: verify the mains voltage and ensure the unit’s internal fuse is intact; inspect all wiring harnesses for corrosion or loose terminals; and test the high‑voltage output with a multimeter set to AC measurement while the controller is powered on, confirming that the expected joule rating is achieved.[oss-gpt-20b]
