Navico PH-8000 Autopilot
I have just bought a Jeanneau SO 37.2. It has a Navico PH-8000 autopilot. The pilot when it works is reasonably good. It is however intermittant. The problem appears to be the PC-8000 controller. I am looking for schematic and specs on components. The circuit is simple but I need the voltage rating on the zener diode in the LED portion of the circuit. I will replace the whole autopilot at some point in the future in the mean time I am trying to get reliable operation back at minimal cost.
