Purchased new. Just unpacked and my receiver T111 T112 does not display information from speed and depth
transducers. Power + - to transmitter is good. No power at the speed and depth
exit wires from the hull
Stumped, and not getting good help from manufacturer. This device was purchased new from Defenders for a backup since we were out cruising for several months. Pulled boat
to install and cannot get it to work. Am I missing something? Douglas Redding, Captain
"Nebula" Niagara Sailboat. Sure would appreciate some help.
