    Command Link gateway to display 2019 Yamaha engine data on Raymarine Axiom MFD stopped working - troubleshooting help

    1. check all fuses - all worked - 1 on RED power cable to CL hub from remote control.
    2. I removed the back cover of CL multi-hub and found 11.2 volts on the 2 long stainless steel plates inside the CL multi-hub (Unsure if 11.2 is enough to power all the plugs on CM multi-hub

    I don't know what effect it would have on the Gateway -
    but certainly,
    measuring 11.2 volts there - or anywhere - is "pathological"

    what is the voltage at the battery terminals?
    12 and change, yes?
    you should have within a couple of tenths of that,
    on the red power cable -
    and the same on the hot terminals of the multi-hub

      here is a picture to make sure 12 volts power inside of the CL multi-hub - see picture below.

        Yes, my 12 volts battery is dying and measured only 11.2 volts so silly me. I connect it to a 12.75 volts battery and I am getting 12.50 volts so good for this part. Moving on to check the power inside of the different cables:
        (1) cable to Yamaha 70 hp engine bay - I heard humming sound when turning my key so this cable should be good.
        (2) cable to Yamaha gateway 6YG-8A2D0-00-00 - To be checked.

        How do I check data wires in these cables?
        How do I check NEMA 2000 cables and T-connectors?

          Yamaha 'Command Link' is essentially NMEA 2000
          so four conductors:
          red=12V+,
          black=ground,
          and the blue and the white are the data wires.

          The wiring for NMEA 2000/Command Link,
          when properly configured,
          is arranged in a "backbone" - with,
          at each end, the white and the blue wires connected via a 120 ohm resistor
          like so:




          as far as testing 'data wires'
          with all the devices 'off',
          you should have:
          - continuity between all whites,
          - continuity between all blues,
          - a 60 ohm resistance between white and blue, anywhere


          By the way -
          ​​​​​​​I didn't see what Yamaha model you are working with;
          but, although Yamaha 'assumes' you will use their Gateway -
          if the engine is 'mechanical control' -
          NOT "DEC" / 'drive by wire' -
          then you really don't need the Yamaha Gateway -
          just connect up without it.

            I am connecting it to Raymarine Axiom 9" MFD multi-function display instead of Yamaha digital meters. Yes,F70 engine is mechanically control instead of DEC/drive by wire. That is why I need 6YG-8A2D0 gateway to relay F70 digital engine data to my Raymarine MFD. It was working until this weekend. The other thing was it would stop displaying when I put Remote Control into gear. There may be loose connection somewhere in the wiring because the trim display showed solid blue color when I was moving the wires to see which wire was loose. Too bad, the blue trim color in the trim bar didn't stay long enough and it didn't turn into yellow and stay yellow. I know SOLID yellow in trim bar means engine data is displayed.

              here is the setup picture - note the yellow trim bar in the MFD

                I can't imagine why you would see a problem from putting engine in gear -

                but if you have your connections arranged as that photo shows -
                without termination resistors on the Yamaha multi-hub -
                its a miracle if it works at all

                  Correct! It would not work without the 2 resistors.

                  whats weird was the trim color showed solid blue for 5 seconds and then disappear.
                  i don’t remember whether it will turn to yellow if i had a good connection.
                  i know it would turn to yellow for the trim bar when it was working.

                      How do you check to see whether the 6YG-8A2D0-00-00 is working or not? I didn't find any loose connections in all the wires.

                        I tried connecting the F70LA outboard to NMEA2000 with Yamaha engine interface cable without Yamaha gateway 6YG-8A2D0-00-00 but no display on my Raymarine Axiom MFD earlier. That's why I bought the Yamaha gateway but now the gateway seems to be broken. How do i check it?

                          Please help Yamaha outboard parts forum viewers if you know a better way or you see what I am doing wrong. I checked the voltage of multi-hub but power for multi-hub and NEMA2000 backbone until now. Here is what I did to share and help others.
                          ok, a light tester tool is a must have to troubleshoot boat electronics. I was able to find 12v power in all my CL Yamaha multi-hub and NMEA2000 cables so fuses are checked. The only thing left to check is a NMEA2000 data reader like Actisense usb to CAN bus dongle to read my F70 outboard engine data to a Laptop or DIY build a reader using Arduino or Raspberry Pi 3b plus to read data and display on a laptop or computer monitor. I will post a NEMA2000 cables power check later. So far everything checks out, so I am beginning to think my Yamaha CL data gateway is broken and needs to be replaced. Luckily it is still within 1 year of Yamaha parts warranty.

                            good luck with getting a warranty on electrical stuff, most places say no.
                            too many people screwing things up and then returning them or at least trying to.

                            also a test light works to some degree, but it cannot tell the difference in 10,11, or 12 volts.
                            it just says you have some power.
                            volt meters are a lot better

                              I found my problem i think. Please confirm. My Yamaha 70 hp ECM electronic control module needs a reset. The can (control area network) bus stopped transmitting data at my last trip when my battery died. I shared my starting motor with it my 24 volts *****ing motor. I had to switch my starting motor with my 35 amh motor for fishfinder and started the motor up and went to the ramp.
                              is there a way i can reset the code in F70 without visiting the dealer? I think they charge an hour labor for hooking up to the computer. You can buy engine reader like OBD II code reader and reset the code, so i wonder if there is such a thing for boat engine.
