boat electrical problem - stump the chump edition UPDATED

Posted on 9/1/17 at 7:09 pm
i have 12 volts to the fuse block, 12 across the fuse block, 12 volts from the hot side of the fuse block to every fuse, continuity - not 12 volts - from the ground/black side of the fuse block back to the battery. my conclusion is bad ground. i put in a new ground wire and still don't have power. wtf?
i have checked the battery, it has 12 volts
from the battery to the perko is 12 volts
across the perko is 12 volts
from the perko to the fuse block is 12 volts
across the fuse block is 12 volts
tia and for your effort enjoy:
turns out that i made a mistake. i didn't have power to the fuse block as i origionally thought. problem solved.
i was testing for power to the block by touching the perko (which has 12 volts) and the hot/red side of the block. all i was doing then was confirming 12 volts at the perko.
not sure if im explaining this correctly

Judging by the pic you are over fused!

So everything on the block it down?

all the fuses on the block are fine - not blown. but nothing works: no vhf, no gps/depth finder, no aerators, no running lights, no radio, no bilge, no power pole.
the outboard is wired directly to the battery and will crank and trim up/down

Probably getting a back feed thru your on board stuff reading 12v. Sounds like, as always a ground problem. Secondary system boat wise? I would guess loose connection, but that's just me.

I don't know how DIY you are, but you can bypass the battery feed after disconnecting it from the terminals and refeed. Meaning bypass the feed to the fuse block to the battery.

Find a new ground location would be my first test.

i think i know what you are saying. isn't that what i did when i put in a temp jumper for the ground wire?

Either bad ground or you got a house fuse somewhere back towards the battery. Mine is mounted on the backside of the transom near my battery switch.

why wouldn't you ground back to the negative terminal on the battery?

How many battery's onboard?
If you have two make sure you are using the ground (negative) from the same battery that your are powering the fuse block. You could also tie the grounds together.

3 batteries, but 2 of them for the 24 volt trolling motor only. i'm positive there is no connection between them. the 2 trolling motor batteries are inside the console and the starting battery with accessories is in the rear of the boat.
i'm really at a loss here.
edit for hogdaddy's question:
i'm certain the grounds are not "confused". everything was working fine till a few weeks ago. i thought the ground may have rubbed on something and developed a fault. but with a new ground in place and the same thing happening?????

You sure your volts are good , battery ?
A fully charged battery should/can read 13.5 v

Not thinking this is it, BUT... make sure everything you're testing is rum from the battery that you're working with...
Ive made that mistake.

Is your kill switch all the way plugged in?
Posted on 9/2/17 at 5:14 am to weisertiger
yep, the outboard starts and runs fine

12 across the fuse block
When you say 12 volts accross the fuse. Are you putting your test leads across the fuse itself getting 12 volts?
If you are it's blown. You should get zero volts across the fuse if it's good meaning you have no potential and are essentially reading your leads as shorted. If the fuse is open you will read 12 volts directly across the fuse.
It can trick somepeople.

Ya, id switch the multimeter to resistance if he cant visually see that its blown. Be real easy then.
