Fish finder individual circuit?
Gents
Does a fish finder need to be on a completely independent circuit?
Fact is I'm grasping at straws a bit. I just got off Garmin tech support and there is nothing they can tell me I have not done.
Still under warranty ☺.
Symptoms are unit barely reading bottom. Not revealing any structure, no arches,. Even max gain will not wash it out.
840xs.
Transducer is ticking away strongly.
Unit hangs up, barely moves , or moves but barely shows bottom and is of no use right now.
I will remount back to transom (on TM now).
Reconnect it to separate battery
Transducer is TM150M
Thanks

Did it work correctly when it was on the transom?

Don't know that it will solve your problem, but yes run you a separate circuit for each finder. I run a twisted pair of 12 gauge wires to help reduce chance of interference. These new finders require quite a bit of juice to work right. And they do some crazy stuff with low voltage.

Cray is right about running a twister pair.

Ok
twist red & black from fuse box to finder?
or all the way from battery to finder?

From battery to finder ... with a blade type fuse in the positive wire at the battery end ...Originally Posted by brettw
Every connection added between these 2 points adds more voltage drop across the length of the entire circuit ...

I doubt that this is your issue. You are more than likely apt to have a bad unit.
I don't like to use the fuse panel because of what was mentioned above. I do however hook to the wiring block that is under the helm of my boat. The difference is that I personally wired this block direct to the battery (positive and negative side) and know that the wire will support anything I put on it. Sometimes, manufacturers wire their fuse panels with mediocre wire. Plus, you have your gauges, livewell, bilge, nav lights, and everything else potentially drawing power from the panel.
I use a wiring block just the lesson the amount of runs directly to the battery. There is a formula based on the amount of amps and distance from the battery as to the size wire you will use.
That said, send her back, I'd bet it is a faulty unit built on a Friday afternoon by a guy that was ready to hit his own boat and fish!!!

Yes,
last year , it was working well on the transom.
I'm moving it back but I can't figure out how it will help.
I have everything turned off and the transducer is just hanging on the TM when testing.
It's the same as having it on a stick.
One thing I am also going to do is put it on its own separate battery. I got one of those small ones and I ran if off that one last year.
thanks guys,
I'll post results next week when I can get out,
