I'm refitting all the electronics
in my boat right now with a full suite of B&G gear
including their AC42N autopilot
computer. I'm replacing a Robertson/Simrad J300X-40. It's not obvious how the new computer should connect to the hydraulic drive components. The pump itself is only a few years old but I can't quite see the brand/model number the way it is installed. There appears to be an electronic valve that changes the fluid flow to the ram.
The manual is sadly unclear on connecting to an older system.
Old wires are labeled:
- "Pilot Sol-Motor" (obviously sol = solenoid)
- "Pilot Bypass clutch"
New computer has connections labeled
- "Drive" - two posts, no polarity
- "Drive engage" - two posts + and -
My guess is I connect "Sol-Motor" to "Drive", and the other two to each other, but I'd rather not guess. I'm not very familiar with these systems so not even sure if they are even meant to work together.
Any experience/advice here?
