Hi,
I'm in the midst of replacing a fish finder on my 19'7" Neptune Sunbird center console boat The original fish finder is a Hummingbird. Here's the question:
There's a black toggle switch on the right side of the console and I haven't a clue what it controls? Can anyone tell me?
The transponder and water temp sensor run to a siliver colored small rectangular box underneath the console. From this very hard to reach box, the wires run into the accessible compartment the radio sits in. Can anyone tell me what the purpose of this small silver box is? How can I get to it?
