I have not forgotten you! Just got busy with other projects. I am going to have to pull a panel off tomorrow to try to trace the wires from the VDO gauge. I did pull the cover off the control panel
but that didn't help.
My rudder position is relayed to the unit by a rudder sensor at the motor
..its an outboard
but I just don't remember how it is wired at the control box
The control unit at the pump just burned out on mine this month. I don't know if I will try to find parts
for it or replace the whole unit. The last time I needed a flux gate compass
, I really had a difficult time finding the part. Navico
no longer supports the unit as it is so old.
