[CA] [CA11] Merging old and New

Chuck,

It initially ran great, but I've run into a snag. Initial installation was a single Axiom RV (E70367) with adapter to the Airmar triducer. Axiom detected it and I was able to receive and display sonar data.

When I installed the second Axiom (E70366), the RV unit never detected the transducer again.

Steps I've taken:

-Did a break and make on all connections and visually looked for bent pins, etc.
-Ensured both Axioms on the most current L3 version (3.7.70)
-Performed a complete factory reset on both units
-Performed another factory reset and only hooked up the original Axiom RV unit (did not network to the second unit)

Granted, the transducer could have suddenly died, but it was working with no issues leading up to this so I'd still like to see if I can make it work for the time being. Are there any accessible onboard diags that could dig a bit deeper?
