12v accessory plug

[Specialk1302]

I have seen other posts similar to this, but they have not answered my question. I want to install a 12v accessory plug in my boat to plug my ipod transmitter into. I already wired the ground wire for the plug to the fuse ground bus. The CD player/radio for the boat is already wired into a 20a accessory fuse so I tried to wire the accessory plug in the same fuse as well. It blew the fuse right a way. I need to figure out a way to wire it to where the accessory plug will be supplied with power whenever the key is turned (even if not running).

Thanks

"fuse ground bus"

That is not a ground, it is + battery hot. What color wires are connected to the buss?

"That is not a ground, it is + battery hot."
Which would aslo explain why your popping a 20A fuse off a basic (low mp draw) radio.
Recheck your wiring and use a voltage meter to determine what's hot and what's not.

Re: 12v accessory plug

all the wires connected to it are black. maybe it isnt a "buss", but is the area next to the fuse block that has all the black wires connected to it

Re: 12v accessory plug

O/k, black wires usually mean ground but you said it was fused. Ground busses don't have fuses.

wee hooker is right, you need to confirm what is hot and what is ground before you connect. Probe the buss.

Re: 12v accessory plug

don't know if this will help or not....

this is a pic of my aftermarket fuse panel after install. yours will no doubt look different, but the principle will be the same. this panel is always live power. the feed wires run all the way to the batt. the red (+) wire is fused with a large fuse right at the batt.

you can see the big fat read wire (+) at the top of the panel and the big fat black wire (-)at the bottom. these are the (+) and (-) feed wires to the panel.

sorry the pic is not with the cover off. but the two black wires (on the bottom right) and the one yellow (my colors ain't right either are they) on the left (bottom left) at the bottom of the panel is where all acc. ground (-) wires are attached at. these wires are a direct connection to the big fat black wire for ground.

the two red and 1 yellow wires by the fuses are the positive (+) wires for the acc. i have going to this panel. three are marked as to what they do. the forth is a cigarette lighter 12v supply mounted on the dash. just like you want. anyways, these red and yellow wires in the fuse box are directly linked to the big fat red wire with a fuse in between them..

i agree with others. you need to find out what is what with your vom. it'd be nice if all circuits had their own fuse.

only thing i could have done better was the stacon connector ends. there just crimped on and should probably be soldered on + have some shrink tube put on ea. connection..

hope this helps..

Re: 12v accessory plug

Here is some pictures. I am getting power to the 12v plug now, but when I put the accessory plug in, it blows the fuse in the ipod charger plug. Help?

Re: 12v accessory plug

You do know that the center of the accessory plug is +12v and the outside is -12v? Stick a meter in there and you will still read 12v, but the polarity will be wrong.

What should I do to rig up a way for it to work?

if it were me...

move the blue cd wire to one of the extra terminals ya got and put a connector on it so it plugs on correctly.

fig. out which of the wires for your new acc. are (+). brown or white. give the pos. one a connector and plug it into the other extra slot ya got on your panel. put a connector on the other wire and connect it to the ground side.

put the proper size fuses in the panel for the cd and the 12v acc.

the 12v + side is the wires that are by the fuses with the colored wires on it.
the 12 neg. side is the terminal strip with all the black wires on it..


if the problem is that it becomes switched power at that time. your gonna have to find somewhere else to connect it that has a wire that has 12v to it all the time (non switched power). you can't (shouldn't) put a wire directly into the fuse itself. like the white 12v and blue cd wire appear to be..

my speculation would be that the white wire of your new 12v acc. is the (-) side. since it blows the fuse when you connect the acc. up..

Re: 12v accessory plug

Step #1: Check the socket to see which wire feeds it. I'm betting its the tan wire. You currently have the tan wire connected to ground which would be wrong.
Step #2: Check the socket to see which wire feeds the side or shell. I'm betting its the white wire which you have connected to +12 volt which would be wrong.
Step #3. Get those wires out of the fuse socket and onto the appropriate spade connections. Fuse sockets are intended to hold fuses, not wires jammed into them.
Step #4: Set your meter to the whatever scale will measure 12 volts. Touch the red probe to the center terminal in the socket and the black probe to the side (shell) or to ground. If you have the wiring reversed, an analog meter will try to read in reverse. If it's a digital meter it will read 12 volts with a (-) minus sign in front of the 12 volts.
There are only two wires involved here. This is not rocket science but you do need to have the center terminal on +12V and the ground side on ground. I feel you do not have that currently.

Lastly, you have two empty fuse locations. why not install a new fuse for the socket and use the other one for the blue wire you have jammed into the fuse socket.

First off get those wires out of the fuse slot, as you are bypassing that 20 amp fuse.

Second, it looks like you are wired backwards since you have the red wire going to the ground block.

You've got extra slots, so add a couple of new fuses, one for the CD player, and one for the 12v accessory, crimp a spade connector on each for the spades and slip them on their own respective spades. I'd go with a 5 or 10 amp max fuse for each.

Connect the red wire to the fused slot and the other (white?) to the ground block. The blue for the CD player should go to the other newly fused spade

Re: 12v accessory plug

I'm betting its the tan wire.

must be our computers generating different colors st.. your tan wire looks brown to me...

Re: 12v accessory plug

That wire going to the ground is actually brown. I guess the picture came out bad making it look red. Do you think those extra fuse slots will get power at the turn of the key just like accessory fuse already at use?

if everything else in that fuse block is switched, yes. put a meter on the spare terminals on the block and see if it's live when the
key isn't turned on.
if it isn't. and you have to have the key on to make the terminals live. if it's switched and your gonna have to find somewhere else
that's always on to get the non switched power like you want...

i wanted non switched power too. that's why i ran a two leads all
the way back to the batt. to power my fuse panel. so i'd have non switched. always live 12v for my acc...

Re: 12v accessory plug

Every circuit on that fuse panel operates the same way. +12 volts goes into the fuse panel and powers the line side of every fuse in the panel. The load side of every fuse is what those spade terminals represents. They are there for your use. Why not use them rather than stuffing wires where they don't belong. You do obviously have to stick a fuse in the empty slot.

Re: 12v accessory plug

I'll repeat. Get a ($3) volt meter in there. Everything else is just guess work based on wire color.
