help with wiring

[heckvr4 2]

i need some help wiring my DC POWER DUAL BRACKET/alternator on my 05 f150 5.4l. I know its pcm controlled. so i dont want to fry anything in my truck

its there a diagram i can follow ?

i already have it installed..

i have the relay conected to the battery, grounded and ignition,

WHAT ESLE DO I NEED TO WIRE???...

please help, if you need more info letme know.

thanks

btw the realy does not showon this pic , but its wired just like i said.

anybody ?

it might be a stupid question , be we were all stupid once rigth ? lol...

Looks like you need to put the belt back on

Do you have wire (1/0) going from the output stud to the positive terminal on your battery?

[heckvr4 2]

Good eye.. yeah the belt its installed.

Should i have a wire from my dc alt to my front battery? Or my back batterys?

Thatz the confussing part for me...

Can someone from DC confirm?

When I wired my dc alt up, there was a small red wire for ignition (low amperage signal sent to alt to turn on and produce power) and a small white wire (grounded to engine or body). There was also a small blue wire but it was short and just went on output stud.

the actual alt case is the entire grounding point for everything being charged, so once the alt is installed in the bay, it's grounded and what not.

Now you may have some extra wiring for bypassing pcm that stuff.

Next, you need some big wire w/ring terminal to go from the output stud (copper stud with threads) to your batteries.

Is this second alt 14v or 16v setup? Is it being used for charging the stock electrical as well, or just the stereo? <-Depending on this, will depend where the big wire from the output stud will go (either front battery(s), or rear).

[heckvr4 2]

second alt its a 14v setup to charge my back batterys.

so i should have my 0g wire running from the DC alt to my back batterys.

do i need a wire from the DC alt to my front battery ?? besides the relay wire ?

sorry , seems so easy to do . like i said i want to be 100% sure of what im doing....

thanks for the help so far stephan

I just want to clarify so we aren't confused, by 14v, your rear batteries are 12v and charge at 14.4v (although alt will likely charge at 15v)

yes , sorry about that.

Well I'm positive you can run a big wire (0/1) from the output stud to the rear(where just your stereo batteries are). The wire would connect to the positive terminal on the closest battery in the rear. The negative terminal on the batteries would be grounded to the frame.

I would do the above because it would allow your h/o alt to charge and supply amperage directly to your stereo. Your stock alt should be able to run your stock electrical system with no issues.

Plus I'm not sure what happens if you mix a stock alt and h/o alt to the same electrical system, one is charging at 13.5v-14.4v(stock alt) while the h/o alt will be doing 14.4v-15.4v (h/o alt). I have no experience with trying to do this.

thats exactly what i was thinking, but some of my friends told me that i needed a wire from the dc alt to my front battery too...

just wanted to confirm....

i guess ill try it huh ?...

[Shogen 325]

Did you email or call DC? You need a more solid answer since stef admits not being experienced to this point... If you do get an answer from DC pls post it for the rest to gain the knowledge as well.. I would like to know as well...

Your stock alt is still wired up right? As long as you didn't disconnect your stock alt in any way then it should charge your front battery and maintain your cars electrical system and headunit.

Then your h/o alt will charge your batteries in the rear and supply amperage to all your amps.

I'm simply stating I don't know about mixing the stock alt and dc alt on the same electrical system.

But I am 100% positive about wiring to the rear for just the amps and batteries not connected to the stock electrical.

Believe it or not, but a lot of people install this stuff without the aid of the manufacturer, (I certainty didn't because I had a bypass harness with no instructions, so I had to call up DC Power. Thankfully I can use what I learned and help him out.)

Good luck getting a hold of DC Power

Nah don't take that statement in that way stef... Simply stating you have mentioned it more than once you aren't sure.. I try shit out without help many times but I have a limit... Know what I mean???

Yes, but the way I'm suggesting will work perfect for him as long as his stock alt hasn't been disconnected in any way. He'll then be able to wrap this up and have a vehicle to drive.

[Shogen 325]

oh ok... I'm drinking so maybe I thought this was more complicated than it is???

[ssh 924]

oh ok... I'm drinking so maybe I thought this was more complicated than it is???

For this scenario it's broken down like this:

stock alt charges front starting battery and the cars electrical system, and headunit.

H/O alt has a set of wires, it may or may not have a blue wire, if it does, it goes right on the output stud, idk what its for but I know where it goes.

The red wire is for ignition, can be hooked up to the ignition wire going to the stock alt, or directly into the fuse box to some extra ignition relay.

The white wire is ground, ground it to the frame or engine chassis.

I don't believe he has a bypass harness since the h/o alt won't be connected to the stock electrical.

Now you just run your big wire from the output stud on the h/o alt to the positive terminal on the rear battery(s). Negative terminals should be grounded to frame with equivalent big wire (0/1)

Start it up, stock alt does it's normal job, signal is sent from tapped ignition source to h/o alt, h/o alt "wakes up" and starts charging the batteries in the rear and supplying power to anything connected to the rear batteries.

Run your remote turn on wire from your headunit to your amps as usual, and connect your B+ (power) to the positive terminals on the rear batts and the amp negative/ground to either chassis or rear negative battery terminals.

It's my bed time.

[Shogen 325]

Ahhh... I guess in one post it is easier to follow... lolz

[ssh 924]

Good luck OP, post back if anything is unclear or need more help.

[heckvr4 2]

eveything its clear now, i think.

i finished wiring everything up just like you said, wich was my original plan btw

the stock alt its still coneccted.

i just want to make sure my dc alt its working with just the realy wires.

[Shogen 325]

good luck... Your system looks like it would tear up my interior... lol

[heckvr4 2]

red wire its from my big 3, alt to batt

bluewire goes from dc alt to back batteries.

and im not sure if u can see the relay on the pic ,

but it has 1 red cable to the dc alt stud ,1 white ground wire , 1 red ignition wire and the yellow wire to the dc alt plug,.

heres a back shot of my box. i was gonna do a build log but got laaaazzy... lol

thanksfor the help guys , gottA love SSA.

So the big red wire is between the alt case and engine chassis? Kinda unnecessary but it won't pose any problems.

I only see one small red wire. Is the second one behind the relay that's zip tied?

Did you wire the red ignition wire to an aux switched 12v in the fuse box? Or tapped into stock alt ignition wiring?

The one small red wire I see, looks like it connects to a blue/purple wire and then goes directly into the front battery. <-Is this the ignition wire? If so, it shouldn't be on constant 12v.

-the big red wire goes from the stock alternator to my front battery (big 3)

-theres 2 red wires coming from the relay, 1 goes to the stud on my dc alt and the other its ignition.

- i tapped into the fusebox

-that wire that goes from red to blue its my ignition wire , i tapped into the fusebox, so it does get constant 12v.

Thanks for the help. i hope my DC ALT does not give me problems in the future...

Just so were clear, the ignition wire should only receive 12v when the vehicle is on.
