wiring 3 graphs and livescope

[bassin74]

I will be wiring up 2 humminbird helix 12s, garmin 106ultra and livescope 34. going run everything back to the battery. will be using 10 gauge wire. 2 graphs on bow and 1 on console. my plan is to run everything back to the battery to a on and off switch. will be using inline fuses. are those inline fuses from sea clear worth it? im considering using those solder seal connectors for my install. does this sound like a solid plan? what else do I need to buy besides wire and the switch? are those solder seal connectors step down like 10-12? thanks

[bassin74]

can anyone help me out here? I just read some don't like using inline fuses? if I were to do a fuse block i might keep it in battery compartment? can 8 gauge wire be ran to fuse black as the power wire? thanks

I would do a 4 gauge red wire in about 1-3ft of length to a large on/off switch mounted where you have room and particularly somewhere protected from water running in the back hatch. Then coming out of the on/off switch I would directly have an in-line fuse at 10 gauge for each component on your system with the appropriate fuse size for each graph or accessory. So a grand total of 4 fuses for your setup. I would then use a heat shrink butt connector to connect the fuses to your main 10 gauge run to each unit up the hull. Then get some step down butt connectors from 10 gauge down to about 14 -16 gauge or smaller if possible to accommodate the factory power cable.

you don’t have to use these exact parts as I just did a quick search to show you what parts I’m referring to but this is how I would do it. I personally like this setup more than fuse panels and what not. I like individual circuits coming from a common place right at the battery.

Hey Tim, long time no talk! I need more crankbaits! HAHA

thank you so much. would 6 gauge wire be ok instead of 4 gauge?

I ran 8ga from the Battery to a Blue Seas Fuse panel I mounted on the underside of the front locker lid, then ran 10ga to each component. 3 Graphs and a Hydrowave. Easy to access and expandable.

Yea probably be fine.

How did you attach the 10awg to the graph power wire (18awg)?

Don’t you think the 3 graphs on 8 gauge is going to overload that circuit from the fuse panel to the battery and have a voltage drop? I guess it matters how much power consumption your graphs use.

I used Heat Shrink Bullet Connectors

No, there is not that much draw. Each is fused with 5 amp fuse. And there doesn't seem to be any voltage drop. It's much cleaner than getting power off of a Buss Bar that has who knows how many other components on that line. I used to have the graphs "Flash" when I would start the big motor towards the end of the day. Now, that's not happening anymore.

Step down connectors, double the 18awg?

No way it will overload 8 gauge, 8 could feed 4 16 and a few other items without excessive drop.

I ran 8 gauge from the battery to a Blue Sea Buss at the bow. This feeds a Helix 12, Helix 10, Garmin 1222, Mega 360 and Livescope. I wasn't aware of the step down connectors and was never able to successfully connect 18 gauge to heavier wire. I thought the buss was a good solution.

yes 4 is overkill

Use a non-insulated seamless butt connector, strip the small wire to pass all the way through the butt connector then insert the large wire which will only go halfway thru. This provides good overlap of the wires and proper crimp it be a strong connection. Insulate with shrink tubing.

Leon, couldn’t I use this to connect 1 graph power and ground to 10awg going to fuse box instead of butt connectors?

Yes sir if preferred
