Maybe help with my wiring diagram?

[arkansasnative]

Ive been working on this all morning and i still have a few questions...

1. I plan on using 14 guage TO the switch panel and out TO each item. Will that be enough to carry the loads? They will all be connected to my mini batteries. The only thing on the Deep cycle is the trolling motor.

2. What size inline fuses do i need to use for each item? Specifically the trolling motor.

3. Where can i get some small but bright LED lights ON THE CHEAP?

If anyone can make suggestions to putting this all together and making it cleaner please let me know!

your items should be fuse protected per item, each has suggestions of its own size fuse such as fish finders etc, Lights i would think 15 amp fuse would be adequate, all tho i would run 12 ga wire minimum if it was me, as for the trolling motor min kota makes a 50 amp circuit breaker specifically for t motors.

each item is planned to be fuse protected... that is what the little boxes on top of the switch panel (where the wires are coming out) are.

I mean each item should be fuse sized per specific item, Like a eagle 320 fish finder recommends a 4 amp fuse.

ok... i've got another couple of questions but i'm still gonna try to search and find them.

1. My fishfinder Garmin 140 already has an inline fuse holder with a 2amp fuse in it in the wiring harness. do i need to add another inline fuse between this and the battery?

2. What gauge and fuse has everybody been using for auxillary lights? (still looking for a place to get some for cheap!)

Here is a LINK to a wire gauge calculator. https://www.marine-electronics-reviews.com/boat-wire.html

As others have said above....every device has its own different amp draw and fuse requirements. If a FishFinder calls for a 4 amp fuse...that exact size is what is needed to protect the device...and/or..to protect your boat's wiring.

If a short or internal problem occurs...you want the fuse to blow. If you have too high of an amp rated fuse in line...then your device or the wiring will burn out because the fuse didn't blow fast enough. Your boat could burn up if the too high rated fuse didn't do its job. Sooner or later the very high amps coming off the battery will melt the wiring and cause a bigger problem.

If you installed too small of a fuse...i.e maybe only one amp when you need four amps,...when you turn the device on, the fuse will blow automatically.

You will have to either look up, or calculate, the needed fuse size/amp draw for every device that you add.

Amps = watts divided by volts.
