DFF1/tz14 no “sounder” icon

[Maui]

Aloha all,
I have tz touch 14 with a DFF1 system.
Everything was working great last trip. I was doing some coordinates on land with my tz14 so I went to “sounder” on main menu and hit off.
Then after that unplugged my monitor to do some fiberglass work on boat. After work on boat was done
I plugged my tz14 back in as usual.
Then powered everything up to test it, went to test everything to make sure it was working, I noticed my “sounder”
Icon wasn’t showing.
My light on the DFF1 isn’t showing anything.
Power cables look okay.

Is the a “network” cable from DFF1-tz14 issue or a DFF1 power issue?

Please let me know your thoughts. I checked cables and everything looked good and clean

If it was working before it shouldn't be the mode settings on the sounder. If the light on the sounder is totally out it seems you don't have power. The power should be check at the DFF1 connector and any fuses and breakers check associated with that power cable.

Seems I have the same issue actually....and I tested the power and ground on the power cable coming into the DFF1 box and it seems I have good ground and 13.1-13.2 volts on the hot wire. Unless the little black connector plug somehow went bad, but looks fine. Is there an internal fuse inside the black box maybe?

Checking the "hot wire" means little if there is no load applied. Current behind the voltage is very important, although if you have voltage right at the connection it does show the inline fuses (on the power cable) are good. While you said it was working previously, you still might want to double check the MODE switches on the front of the sounder to ensure they are set to DWN UP UP DWN.
