The International Electric Weed Chopper Electric Fencer is a vintage high‑voltage charger designed to deliver a pulsed DC output for weed control and livestock fencing. Common failures on this class of units include degraded insulation or dielectric breakdown in the transformer windings, corrosion or loose connections at the 110 VAC input terminals, and failure of the internal rectifier bridge due to moisture ingress. Additionally, the built‑in lamp indicator may cease flashing if the charging relay or control circuit has burned out. First‑check diagnostics: verify that 110 VAC is present at the inlet; inspect all wiring for continuity and corrosion; examine the transformer and rectifier for visible damage or overheating; and review any error codes or lamp status indicators to confirm proper relay operation.[oss-gpt-20b]
