The Robertson J1000B 20178075 is an autpilot junction box designed for 12 V marine autopilots such as Simrad AP2500 and R2500. Common failure points in this class of devices include degraded solder joints on the power input, corrosion of the 12 V connectors, and failure of the internal relays that route heading signals to the autopilot head unit. First‑check diagnostics should verify a clean 12 V supply at the junction box terminals, inspect all connector pins for signs of oxidation or mechanical damage, and review any error codes transmitted from the head unit to the junction box.[oss-gpt-20b] |
