[CA] Issues w Fishfinder and Axiom MFD

[moonzy1]

I have recently upgraded my Raymarine network.

Axiom 9" x3 - new 2 months and updated before install
CP370 - new this year
Airmar M260 in hull - 12 yrs old

When the Axioms were installed all worked w fishfinder properly.

Occasionally the fishfinder would lose the bottom and read sporadic shallow depths w a confused screen while in 125' of water. Usually within minutes this would pass and return to normal.

A couple of weeks ago, it did the same thing but would not return to normal after an hour. I unplugged the transducer from the CP370 and plugged it back in to try to see if that would help. The MFD never detected the transducer after that and I dont believe the ducer was powering up after that.

I assumed the transducer was damaged so I purchased a new one and hooked it up to the network and it did not turn on.

I replaced the CP370 to see if that was damaged and no change. Still not working.

I swapped out network cables to test and still nothing.

Im not sure where to go next on this

Any suggestions?
