How to wire in a fishfinder

[johnlsonderegger]

I have an Ebbtide 2200 SS Fun Cruiser and am installing a fishfinder. I would like to use the existing power at the dashboard. I one of the switches is not being used because my boat does not have the fresh water system. I am planning on removing the plate below the dashboard to gain access. Does anyone have experience in this area on this boat?

The actual fish finder had an on off switch built in, no need to be redundant just hard wire to the battery.

.......The red wire to the instrument panel from the fuse box or directly from the wiring harness.....supplies power to the Off-On-Start switch in the console and usually is also a red wire over to the fuse block if your boat has one.
As DeepC said the unit comes with an ON-OFF switch.

Sometimes when running power thru the rest if the boat's electrical system it can cause interference or false readings on the screen of the FF. Most all mfgrs recommend wiring direct to the battery with an inline fuse.

I use a lawn tractor battery under the helm for my Hummingbird and Stereo. I wire directly to the battery.

I do not know any Charter boats on Lake Ontario that hard wire anything but there bilge pump into the battery. ALL electronic instruments are wired into the dash , with a circuit breaker . None of them experience any kind of electrical interference . This includes , radar ,auto pilot , downriggers that have electronic displays , MFDs , FishHawks that give you depth reading and speed at your rigger ball , stereos, two way radios , etc , you name it and its tied into the dashboard wiring system .
