Supercheap dual battery system

There's no terminals on them - they are posts with nuts and anti vibration washers. Different brand maybe?

Supercheap says it all, have a look at Redarc.

I bought a Redarc off Derek on here and used some of my old 2 Gauge stereo wire and fitted it myself and it all cost about $175..

Wouldnt dream of paying $190 to anyone to fit one of those.

Hi Graham,

$190 for 2 hours work for 2 people is cheap. All wires are protected from sticks and rocks and any wires that go thru bodywork have grommets to protect them. They used quality gear and did a 1st rate job.

My battery is located under the tray. Not sure what 2 gauge stereo wire is but if its not the correct thickness wire, you'll have voltage drop.

I believe 6mm is the minimum

Agreed with Derek's gear being good stuff.

AGree get the redarc, These are now available through ARB as well so should you have an issue you have support Australia wide.

As said above 2 gauge is way too thin. Funny those that complain about what others charge are also the ones who do it as cheaply as possible. Ofyten the same ones who whinge how much extra someone else somewhere down the track charges to sort out the mess.

Do it right, do it once.

Back to school boys

Just so you know the smaller the number the heavier the gauge in DC Power cable

2 gauge is total diam 12mm and has a current rating of 160 amp

Costs $18 a metre for the type I had of oxygen free stuff prev used in a high quality stereo

4 gauge is 10mm total diam, current ratiing 110amp

8 gauge is 6.5mm dia and 56amp curent rating

So where did I use too light a wire and do anything on the cheap.

The wires have professionally crimped ends and are fitted very neatly and cable tied to stop any vibration They have done 55,000km in the last 13 months without any trouble whatever

I did it once and has proved to be done right

You are talking automotive weights and 2mm would be speaker wire 6mm is usually whats provided in a Waeco fridge extension wire.

But are vastly different to what I used.

There endeth the lesson LOL.

To give you an idea here is a 5AG Fuse holder with some 2 gauge cable in one end
Heavy enough do you reckon

Hi graham,

Its good to see you used the correct wiring and i assume you have the knowledge to install it correctly.

Thats good i dont have the knowledge and think getting someone who does to do it for me is a little price to pay for the piece of mind when im down the worst track imaginable that something wont stuff up due to bad workmanship.

I believe Ive got the knowledge to patch something up if it does break and i think i can patch it up.

$190 bucks works for me.

Cheers Wilko

Here is the Redarc fitted and a pic of the actual "too light " cable

What is "2 Gauge cable" ??

In AWG the diameter goes up as the gauge reduces, for metric gauges it is the opposite.

This is where it came from and the pic above is the 2 g oxygen free cable as I said, was about $18 a metre

I guess they know what they are talking about an as you say the thicker the wire the lower the gauge exactly what I said

If you talk in MM its the other way as 3mm wire is smaller than 6mm wire

Is similar size to 2B&S (32mm²)

Exactly as i Described in follow up no 4 is it not.

Graham,
yes it is, just I'm not used to it being referred as "2 Gauge cable" that is why I have asked the question, but do often get the reference to '2g' which maybe I should have taken as being the same thing, but it just did not happen as it was a bit expensive compared to the RRP of $14.50 per Mtr.

My bad I read 2mm... exactly what I was thinking speaker wire!

Hmm amazing that people see what they want not what is written Not to worry.

Yes Mainey it was expensive as was the 1 farad capacitator that was in the middle of it and the very expensive stereo and amp on the end of it.

It was better quality than sold by Jaycar as well.
However I sold the car and had the wiring left so used it
.Have also got one of those fuses on my fridge circuit using 8g cable and to the batteries using 3 g cable.
On them I have 60 amp resettable fuses at each end at $26 each.

Not cheap to do it once do it right.

Have about 18 m of that sort of cable through the car.

Cheers am getting the solar installed at home next month $1660 for 1.5kw

gbc - All I come up with is a lot of people saying Redarc are great - not many complaints at all

So what is your issue...maybe it was wired wrong :-)

Yeah maybe - not. The 4wd systems isolator is on the same wiring - they were just changed out.
There's a fair few of us around the comp scene who've had some probs - I'm guessing the isolators that are fully sealed (epoxy filled) like the supercheap etc are suiting those of us who submerge etc on a more regular basis than those of us who don't?

The redarcs really are old school (briggs pot?) - then again that's probably why they have such a good following around here?
