2017 Nitro Z21 Pro

For those with the Z21 pro with the 112 Minn Kota....I’m trying to decifer how the batteries are configured. i have 1 cranking battery and 3 trolling motor batteries. My question is where are my 2 Lowrance graphs pulling power? I have a 3rd garmin graph I put on myself for mostly mapping (I like the garmin map set ups better) but cant decide what battery to pull power from. I feel pulling power from one of my 3 trolling motor batteries will pull to much current and toast my graph? By the way....I know nothing about electricy and wiring so I could be completely wrong.

All the electronics should be on the starting battery trolling motor should be on its own.

This is what I was thinking but couldn’t trace the wires from my lowrances.

[Fishysam]

Wires from lowrance go to a fuse block under the dash, the pair of blocks get power from the cranking battery, there should be a couple empty spaces in the blocks for more accessories

[JoeDrb]

Hmmmm that would have been good know seeing as how I already ran my wires straight to the batteries in the back. I’ll have to see if I can even figure out how to draw power from the fuse block to the Garmin.

If you ran the wires already, set up a fuse and use it. This will give cleaner power.

[JoeDrb]

What size fuse do you think is sufficient? I know I can get an in line fuse kit from walmart for pretty cheap.

[jarhead175]

Just guessing 3amp anymore would be bad for the unit.

This is correct. Why not read the owners manual to get the proper fuse amperage?

Agreed
