Woodie, i sent the pic to a close personal friend of mine who is a damn good electrician and who did all the fine wiring on it.

He is pretty confident you have either 1, a bad connection to either the transducer/back of the unit, or #2 just a bad transducer all together. Hopefully its #1

Some of the hummingbirds transducers fit in 2 plugs in the back of the unit. If this is the case, check to make sure its in the right one.
