Default Garmin 741xs not displaying engine data

My Garmin 741xs all of a sudden quit displaying the data from my Suzuki DF60. The Garmin does not list the engine as one of the devices in the "Communications" menu. The connections to the unit seem secure. Any ideas on how to diagnose and fix the prob?

Are there any other devices on your network, and are they showing up on the device list? If not showing, maybe the network power supply has failed? Check fuse and ensure network is being powered.

If network is definitely getting power:

Otherwise, likely that a physical component in the network has failed.

Could be a T piece, could be a broken pin or corroded wire in the interface cable or adapter cable or one of the plugs on them. Lastly, the interface cable could have failed -doesnt happen often, but has happened. But less likely than a broken wire or pin in a plug - that would be the nost likely, followed by a bad T piece, or a pinched/damaged cable.

You will need to disconnect all interface plugs, check wires where they enter plugs carefully, and repair if necessary. The pins come out of the plug quite easily, litte tab you get to from the open end, lift it up then pull the pin out from the back of the plug where the wire connects.

Unplug all T pieces and check inside for corrosion or broken pins. Swap the interface to a different T piece and see if that helps.
