If using a 5 way connector rather than Tees black plugs must be in any open white connections and also in the second white connector on the P70

There will also be a black red cable connected in there to power the thing (unless powered by the switch in ACU mentioned above). Term-|-|-|-termĪnd_ is the cable from the rudder position sensor Your SeaTalkNG network should look like ( order except terminator doest matter How or are the systems communicating NMEA 0183? It's possible when you removed the old electronics you eliminated a blue plug (terminating resister) from the SeaTalkNG network. The EV1 with the P70 ARE SeaTalkNG which IS NMEA 2000 with different connectors. In the setup page on the controller you can choose the data sources. If you already have a power source for the NMEA 2000 and if you are refering to the NMEA 200 power switch on the ACU then turn the NMEA 2000 power switch off on the ACU. You only want one source of power on the NMEA 2000 bus. Some of the ACU units have a switch that when switched on will power up the NMEA 2000 bus. When you mentioned control box, are you referring to the Raymarine autopilot control unit (ACU). I would try your autopilot without the other electronics on and see if the problem goes away, then turn one thing on at a time and see which device if any are causing the issue. Both the EV-1 sensor and the Garmin heading unit may be putting data on the NMEA 200 bus and the autopilot may be confused which data to use. If that is true, why did you add another heading sensor? That may be part of your problem. If your autopilot was working well before, I assume you had a Raymarine EV-1 sensor in your system. If your autopilot was working fine before, then one would naturally think that some of the new Garmin equipment is not playing well with your Raymarine autopilot. Pierce but I would like to see if I can fix it-I think it is probably something simple. I think there is a good Raymarine dealer in Ft. I am on the ICW in Florida heading south and need suggestions. The Raymarine control box has a switch that was 'off' and I moved it to 'on' with no change. ) I moved the 545 antenna and the Vesper antenna a few feet apart (they are both on the stern rail) but there was no change. I am thinking it may be a compass issue (I put the old 545 down below, and I also added a Garmin Heading sensor. When I put the auto pilot on 'standby'' and then back to 'auto' it works fine for another few minutes. Now the auto pilot works for a few minutes and then the boat starts drifting -the screen is lit and pushing direction buttons does nothing. I changed the binnacle Garmin 545 to a Garmin 1040 with radar, added a Garmin thru hull depth finder, and added a Vesper Marine AIS. My 2003 Mark II tall rig/wing keel Catalina Linear Drive P70 auto pilot worked fine until I upgraded the other eletronics.
