Just bought my first graph! Can't wait to install it on the motorguide. Any tips? w,ill be new experience.
Careful with the transducer cable... use some zip ties to keep it from getting pinched in the motor when you raise and lower it into the water. Make sure you get your 12v power from a NON-ignition circuit. In other words... a circuit you don't have to have the key on or the engine running to get power.
Great thanks. I have a battery compartment in the front deck of the 16ft pro tiller smokercraft that houses my 12v battery for my motorguide. I'm thinking about putting my small meijer deepcycle battery next to the 34 class diehard that I have so the diehard wont get drained. Having it on it's on battery would decrease interference right ?
it's not advised to run your graph and trolling motor on the same battery - so yes, good idea.

Yeah, what he said!
Thanks!!!!
Kind of wire should I use?
Planning on running a wire to the back of the boat now. Also what circuit breaker should I use for the graph? I have to replace my short box on my trolling motor as well or shouldi use something else? Anything else I can do to reduce interference I hear can be a problem? Sorry about all the questions.
Make sure you use only marine grade wire (tinned copper). Any other wire will eventually corode and isn't as efficient (can also cause more interference). You can get the right wire at any West Marine store. I would run at least a #10 or #8 wire... less voltage drop with the thicker wire.
Thanks, how would I go about connecting the 10 gauge to 18 gauge humminbird unit?
If you do that, you'll need a twist-on cap maybe. I usually don't mix single wires that are quite a bit different in size but the few times I have, I sometimes double the end of the smaller wire, folded over and crimp that into the larger connector that fits the bigger wire. One possible suggestion.
I like to use liquid electrical tape on some of my splices, crimps, etc to improve corrosion resistance.
I like to run a new wire for my electronics and just put an inline fuse of the size recommended by the manufacturer usually when I do it.
For my GPS/networked graph, I actually spliced in waterproof switches since the wires went to their own connectors on the battery and can be always powered depending upon the GPS receiver you have. That way I can turn them completely off and not worry about battery drain or weird shorts. I used an inline fuse for both and have never had any problems with this setup.
The unit I did this with actually recommended considering a switch because the antennae is always powered otherwise. Not necessarily recommending you do this but just sharing information that worked for me considering the specific recommendations that my unit came with (older Lowrance).
I didn't do this for my newer Humminbird up front. It is not networked and didn't have the same recommendations. I did run its own wire with its own inline fuse back to the starting battery bypassing the fuse blocks. I think I used 14 guage wire. Maybe 12. I have these wires on the opposite side of the boat from the trolling motor wires.

Haha, drink Dos Equis much???

With installation complete no inference and 12.7 v at the head unit!

Ahh...? No. Actually never. Probably tastes like beer. Never liked the taste of beer.
But I did recently stay at a Holiday Inn Express...

Well, you nailed that it sounds like! What did you end up doing?
