I spent most of today completing the wiring for the autopilot install. Yesterday was a shocker when I found out that Garmin has sent me the wrong parts! I ordered the GHP-12 Sailboat Autopilot and got the GHP-10 power boat package. They got the RAM right but that was it.
Ignore all of the images and narrative if this is to boring but trying to pass on installation information to a friend up North who will soon be doing the same installation.
RAM installation is complete - the shelf is 1.75 inches below the fore_aft stringer. I cut some of the stringer out just a bit further aft so that the RAM arm and motor would clear.
Lower view of shelf showing ram/motor clearance.
I cut the power cable very short and terminated the cable on a high current terminal block under the shelf. The power pigtail was about 8 ft long and included a fuse but I needed the fuse at the battery.
CCU/ECU interconnect cable run up along the starboard side under the seats and then back into the engine compartment along the starboard wall. I had to drill two additional holes for these cables in lateral baffles and then one to get up into the lazarette.
New 40 amp fuse and high current relay. Relay is controlled from the DC "electronics" circuit breaker and provides power to the ECU/RAM.
Forward cabin below the floor looking aft. CCU "compass" cable on the left and NMEA 2000 cable (18ft) on the right.
NMEA cable run through two lateral bulkheads the up through the battery compartment and into the space below the breaker panel where the existing NMEA Buss connectors are located. Cable was just long enough!
Final picture of the installed RAM and all cables under the shelf. Cable for RAM power, ECU power, Rudder feedback, CCU/ECU Data.
I mentioned yesterday that I should have positioned the shelf about 3/4" higher - no..... shelf is properly positioned and 3/4" block under the left side of the RAM provides a clear shot into the area under the helm seat.
Next - update drawings and label all cables. Then hopefully the new Core pack will arrive next week.
