Hi everyone, so mich good information here, but cant seem to find my issue. I have a 1992 42 Ocean with the Furuno TZ Touch and the DFF1 sounder. We were out in some rough seas a few days ago and noticed the TZ touch MFD said something about sounder connection lost. Now it's not displaying as an option in my carousel of options on the MFD. I called Furuno tech and they ran me through some initial info, and come to find out there is supposed to be a blinking light on the DFF1 box that I found not to be lit up or blinking at all, which seemed to be that it was off and not power. I used a power probe and traced the 12v power wire and I do have a good ground and 13.2 volts in the wires coming into the DFF1 box but no light. Is there an internal fuse that maybe got blown somehow? Thanks!
