I would back up and try to remember how it quit working. Did both transponders work before you replaced the gauge? Usually its rare that both will fail at the same time but I have had boats that got excessive water in the bilge and took out the units.

the senders hav a paddle wheel in them that can get stuck and not spin thus causing the no reading issue, some times they can be loosened up with air pressure but they will stick again, it appears they might need to be repalced, they retail for 309.00 each. being a forum member you get a 10 % parts discount..

Chad, do your sending units have 3 or 4 screws on the bottom plate?
