Battery Relocation

[MR_N]

NEW question. 06/11/12 Page 2.....

When relocating the battery, i get all that needs to be done with the live wire, using a junction box for the 3 areas. However, what about the earths. I have two on my battery negative. One to chassis (easy to do) and one to the gearbox. Where does the gearbox earth go no the battery is in the boot?

[AlexB]

I used audio stuff cant remember the guage though

Mine doesnt have a distributor block though in the wing fusebox there are 2 attatchments so i have the battery on one then off the other i feed the small fusebox and starter

Made one cable for the second bit with both wires coming off one ring in the smaller box so its tidy and max you can see is one bit of wire

[MR_N]

Any pics of that Alex?

[AlexB]

Not got any mate im gunna be redoing it soon (just tidier) so ill get some

[MR_N]

Thanks buddy. I think ill try it with the distribution block first and try to hide it best i can.

[Jungle]

I used 4 gauge i think. As with dist blocks and fuses etc i didn't mess about with that, just connected the lives that go to the battery in the engine bay to the cable then through to the battery in the boot with a ANL 150A fuse next to the battery.

vehicle wiring products - google it

25mm squared wire should be sufficient

I'll be doing mine soon as per the above. wire from battery to fuse box, then from fuse box to starter. A mate has done his by wiring in a cut off switch. It goes battery to cut off, then 2 wires from the cut off to the fuse box and from the cut off to the starter (this is in an ax so dont have the extra wire talked about above)

[MR_N]

So is it:

Battery -------> Big fuse box-------> Smaller fuse box & Starter
?

[moxy89]

ill be trying this next week!!!! my car is so not going to start

[MR_N]

Let me know how it goes Moxy. Id like to pop down and see how you've done it after

[moxy89]

it will be done very tidy..... however not sure if the car will start but who cares lol

I dont get where all the differnt fuseboxs and fuses are coming from. all your doing is extending the live cable to the battery.

All you need to do is take the battery connector off, and extend it from there to the battery, then put 1 fuse on the cable before you connect to the battery to protect the cable running through the car. Simples. Earth it to whatever is close.

[Gareth_R]

there are two or three wires that connect to the battery, so you can use a distribution block to get those three connected and then run 1 wire to the boot, or the neater way to do it is effectively 'daisy chain' through the car so you run less wires and dont need one of those shitty blocks.

[Jungle]

But all 3 wires go to 1 battery connector, so you can literally just chop that off and connect them to one bigger wire, distribution blocks have fuses in and IMO thats just something that could cause a problem down the line.

[AlexB]

Jungle thats not exatly a tidy way to do it though

The boxes are small one by master cylender big one on the passengers arch

You need 3 lives one for each fuse box and one for the starter

So battery distribution block then fuse boxes starter is the common and probably best way to do it

I went a different route just to try and hide things and not need to find somewere for the block

[Jungle]

It may not be the best looking way to do it but it is the most functional way. As i said all you are doing is moving the battery so all you need to do is extent 1 wire. With an extra fuse to protect that wire. mines tidy as in the live wires in the bay all go to the same place and connect to the main live then to the battery in the boot, you cant see any of it unless your looking for it and its all adequately protected.

I do understand that people like to make it look pretty but im talking purely from a functional point of view. And IMO having extra fuses in is only going to cause problems with them blowing.

Think the conclusion is its all down to personal preference :p

[J222JRA]

Seriously get a jointing box like i have and re-make all the cables so it looks neat. Dont make a shite job Sam your car is quite tidy.....excluding the bumper scuff of course........*chuckles

[Alex]

Hope to do mine soon, Wiring in an FIA kill switch too.
I got some welding wire from eBay, Something like this, http://www.ebay.co.uk/itm/BATTERY-WELDING-CABLE-322-0-30-FLEXIBLE-25MM-AC18B-10M-/280526208280?pt=UK_Hand_Tools_Equipment&hash=item4150aa3d18

[Gareth_R]

It may not be the best looking way to do it but it is the most functional way. As i said all you are doing is moving the battery so all you need to do is extent 1 wire.

but without a distribution block or daisy chaining then how are you going to join them together? you cant just mash it all together and dump some solder on it. or you just leave the original battery connector in place and join on to that and then you have to wrap it in a tonne of insulating tape which would look proper dogshit

then theres no difference IMO between having a distribution block or joining them all together in series. Its still the same number of wires, just looks neater if you join them up.

[Gareth_R]

example

[Jungle]

are they not all joined together just before the battery connector anyway? pretty sure mine were. Im not saying mash them all together, if they are seperate then join them all properly. The point i was getting at was that there is no need to put a fusebox or a fused distribution block in at that point!

Your picture is hilarious...

you cannot put a fuse in main battery cable ,unless you have found some 500amp fuses .--the starter can spike to that amperage on a cold day .
it should go direct to starter and then connect to other parts of car from that same terminal
you cannot fit too large a size of cable as the current will drop the longer the cable .
the more strands in the cable the better the power transfer .
25sqmm is absolute minium bigger + lots of strands will be better.

[Gareth_R]

i thought it as quite good lol

the fuseboxes are already there, you're not adding anything in. and the distribution blocks i've seen arent fused. Its just a physical means of joining everything together reliably.

"are they not all joined together just before the battery connector anyway?"

Not that i've seen, all separate

[Gareth_R]

theres no issue with going to the fuse box then off to the starter - i've seen a number of cars do it, perfectly reliable

Yes you can. I would rather risk my main fuse blowing (never happened yet) than exploding my battery or starting a fire because the sheathing has rubbed through where the cable passes through the shell.

the ones i have seen people have used distrubution blocks used for audi oequipment, these are fused so thats what i was thinking, obviously a non fused dist. block is a perfectly fine way to do it.

Mine was all joined to one so like i said i just chopped the connecter off and joined the two cables together.

[Gareth_R]

fair enough, in that situation it would have been pretty simple

[AlexB]

I never said anything about a fused distribution block or extra fuses

The fuseboxes i mentioned are the standard items in the bay

Your wire will come in and split into 3 the distribution block is simply to split the wires

[AndySAXO]

Hmm just run the cable from the battery to starter motor then run for the starter motor terminal to the two fuse box in the engine bay like they do standard. Also used a kill switch so if you a safe storage place you can kill it so it can't drain the battery.

If installed correctly, and you run the cable correctly and fit it down well, it shouldn't rub on anything.

[Fulch]

I got given this list:

Cable you require: http://www.autoelectricsupplies.co.uk/product/751/category/124

Fuse holder: http://www.autoelectricsupplies.co.uk/product/304/category/62

Fuses, buy two 100amp fuses and use both together to give 200amp blow limit!: http://www.autoelectricsupplies.co.uk/product/291

Relevant clamps for your battery: http://www.autoelectricsupplies.co.uk/product_list/26

Relevant connectors to join to chassis etc! http://www.autoelectricsupplies.co.uk/product/155/category/32

Only thing is I dont know which rate of wire to get

[kyle4256]

so what size of cable is required from engine bay to boot??

[wolf_gsxr]

i might be wrong but running 2 100 amp fuses wudnt that be like running one longer 100amp fuse?

[MR_N]

Seriously get a jointing box like i have and re-make all the cables so it looks neat. Dont make a shite job Sam your car is quite tidy.....excluding the bumper scuff of course........*chuckles

Ill have to do a proper job James. Guess you fed the wire from the battery to the box, then the other 3 for fuse box's and starters from that?
Yes i will remake all the wires as well. Don't fancy using the 13year old originals if i have the chance to replace them.

What jointing box did you use?

Oh and that scuff... im off to the body shop tomorrow lol

Earth negative terminal to shell as close to battery as possible run 25sqmm cable to starter (unfused - use grommets and cowling in any sensitive areas). Run cable from starter to fuse boxes - 16 gauge is plenty for everything after the starter.

If you route the cable correctly you won't ever have it rub. If you're worried about it rubbing, you're not routing it well enough :p

I think you better check the actual power routing ,as no car has a fuse in the mmain starter power supply cable,they don,t make fuses big enough .
the main (maxi) fuses you are referring to do not stop power going to the starter motor --they are for all the other systems .

[jsdvtr]

Is there any earths needed in the engine bay? Like the gearbox.

[MR_N]

Yeah, Gearbox to chassis.

[jsdvtr]

Giot another question -

When using more say 2 ring terminals to one live say on the starter or fusebox, is it ok to use washers to space the ring terminals as they dont sit flat against each other due to the wiring. Or what have other people used?
