Thanks Jon D & Cool Change.
I've done some more trouble shooting and I'm sure the cockpit
control unit is broken and the electronic box may be hosed as well. The electronic brain does send current
to the cockpit controller, but when I push the "turn to port" button the voltages are way off.
Jon, I like your idea of possibly just replacing the electronics (particularly with non-NAVICO electonics). Any ideas on how to check the funtion of the hydraulic ram? I've hooked up the hydraulic pump to 12 volts and it runs, but doesn't move the ram. There is also a solenoid on the pump which is some kind of control valve. When I hooked the solenoid to 12 volts, it clicked, but the ram still didn't move with the motor
running. Do the hydraulic pump and ram need to "be bled" before they will work? This autopilot
probably has not been used in 2-3 yrs.
I've priced new below deck
APs and the cheapest are about $2500 at WM. If I can get the hydraulics working, that would save more than half the cost.
