what size does the 2nd battery need to be? i already have a calcium corsa diesel battery up front, but will be running a dvd system with 2 amps, sub and components. just wanted to leave the ignition on whilst watchin a film or with the system on without having to worry about starting the car!

i've jus got an in-line 140A circuit breaker going to my 2nd battery... my 100A alternator never seems to disagree chargin em both 95% of the time :P
Didnt see the point in getting a split charging relay, dunno if it would have worked so well in my set up

:lol:

cheerz :P

it was when circuit breakers were getting brought into the convo, i lost interest :P

really is that simple then. feel a bit dump now... Feel free to delete the thread :thumbs:

:look:

It dont get easier than that :P

You dont need a diagram because it is literally a piece of piss, what dont you understand?

so i cant be running 0awg through it then...?

i cant find any diagrammes any where :|

agh ok i hadnt got that far lol, ive put my battery in as is for the time being as my cars prob gonna be changed

You have to have an account with CPC though?

How much is the relay at cad??

4 gauge cable is required
suggest a circuit breaker at either end then at least u can flick it off if ever u got in to trouble

and heres a link for a cheaper one me thinks

also look on talkaudio for anyother info chap

Ah right. cheerz. Always learning :)

i wouldnt have thought theres a need for a bigger alternator would you?
as im not going to be playing my system loud lots.

It will charge the second battery all the time, your alternator determines the load.

with only these wires, how does it know when to charge the second battery? Or does it just 'know' and works, and i dont need to question it :|

i wouldn't a thought so, i reckon u could prob get away with 2 or maybe 4awg instead.

You don't really need to run 0awg wire from the main battery to the secondary battery though do you?

No, the charge relay will only have the +0awg wires.

There are two ring connectors which you connect the 0awg to (one lead from your battery or alternator to the relay, then the other lead to the boot), then you have two spade connectors, one for an earth and one for a live to activate the relay

great.

so i have +0awg, -0awg, and ignition live wire going to where the +0awg goes?

kind of hoping this product will contain some diagrammes :look:

Thanks

Its a piece of piss to set it up.

You use ring terminals to connect 0 awg to it.

To operate the relay automatically, you need to connect the positive trigger wire to an ignition live, that goes dead while the starter motor is turning (eg one for your blowers)

If you want to operate it manually, you take an ignition live to a switch, then from the switch to the relay. You dont have to use an ignition live but id advise it so you dont accidentally leave the relay on.

the CAD package just uses ring terminals to bolt it to the relay, so if you were doing it yourself then thats what i would recommend.

although if doing it yourself i would place a "chunky" switch somewhere, just incase you want to turn it off.

Plan on split charging yelow top from boot, and slinging a corsa diesel battery in the front.

This jobby here ---->
doesnt really look like you could feed 0awg through it...
