I am making the jump to one boat network on my new 2021 1750 SuperHwak Crestliner. I finally get the boat this week and did not want to shell 2,000 grand out to do the rig and if something goes wrong I am better understanding of how to fix it.
I have been thinking about where to mount the network and run all my power. I have decided to run power lines off the crank battery with a Blue Sea Systems Fuse Block ST Blade Battery Terminal with 4 Circuits. I ran it on my last boat and it worked great for 2 sonar units with little no draw when not powered. I want to run the network switch on one of the circuits to limit interference. I am no wiring expert, but I pretty sure the switch will have a constant draw on the battery.
What would you do?
1. Put a switch in front of the boat to toggle the switch on off? Inconvenient, but I have to turn the Ultrex on anyway
2. Run power from the console fuse box. Possible interference but I would be able to power switch off when I turn off boat?
3. Bite the bullet and put in a cut-off – My rationale for not wanting to do this is that I like to keep my boat’s main electric separate as much as I can. Something happens to one of those 4 circuits and I still have a working boat and it narrows down my troubleshooting.
4. Has anyone run two cut-offs?
One last question, I am decided to put the BlueTooth puck for the trolling motor at the console. Partially because it should not draw power and secondary less chance of damage. Pro/cons? Am I right in thinking it will not draw power or do I need another switch?
Thanks in advance!
