Mosus Posted April 9, 2007 Report Share Posted April 9, 2007 Hello to everyone Just a Quick Question about relocating the battery to the boot.....basically has anyone done it? Just wondering how hard it was, headaches involved, materials required e.t.c I tried doing a search in all forums and th FAQ but couldn't find anything, if there isn't a TECH article already on it i'd be more than happy to make one as i go, but before i start jst thougt i'd od a bit of research first. Thanks Quote Link to comment Share on other sites More sharing options...
smacko84 Posted April 9, 2007 Report Share Posted April 9, 2007 (edited) yeah i remember there already being a thread on this somewhere... apparently it isnt all that hard... sorry I'm not much more help found the thread http://www.rollaclub.com/board/index.php?s...Battery+In+Boot Edited April 9, 2007 by smacko84 Quote Link to comment Share on other sites More sharing options...
Jono Posted April 9, 2007 Report Share Posted April 9, 2007 not very hard to do. a few points. * use a dry cell battery or you will need to install some type of ventilation to atmosphere outside the car. * a battery box from a boat shop will be cheaper than a car shop * you can run the cables inside the cabin or outside * you can run either two cables (+12v and earth) or just one cable(+12v) * +12v goes to your starter motor * if you use an isolator switch run the wire from the alternator to the line side of the switch (not the load side of the switch) Quote Link to comment Share on other sites More sharing options...
Mosus Posted April 9, 2007 Author Report Share Posted April 9, 2007 Sweet as thanks guys.... i'll give it a shot and we'll see what happens if it all goes to plan i'll take some pics and put up a bit of a tech thread Quote Link to comment Share on other sites More sharing options...
coln72 Posted April 9, 2007 Report Share Posted April 9, 2007 Remember to run big arse cables as the voltage drop will make it a bitch to start if you don't. Use grommets to stop your cables from shorting out when you run them through body work and make sure you bolt your battery down securely.

LINDSAY Posted April 13, 2007 Report Share Posted April 13, 2007 Hey peoples , i am looking at getting this kit :Battery reloc. kit just wondering if this is alot more expensive than getting parts individually for those who have done it allready , i've heard the cable is the expensive part Quote Link to comment Share on other sites More sharing options...
demuire Posted April 13, 2007 Report Share Posted April 13, 2007 if you use an isolator switch run the wire from the alternator to the line side of the switch (not the load side of the switch) I assume by "line side" you mean "battery side"? If so, why? Quote Link to comment Share on other sites More sharing options...
Jono Posted April 13, 2007 Report Share Posted April 13, 2007 (edited) I believe it is so that if you remove the switch it kills the motor, otherwise the alternator will keep providing power to the load side of the switch and keep the motor running i'm sure someone will correct me if i'm wrong. maybe i should try it and we'll find out for sure.

BreakDave - GT Posted April 13, 2007 Report Share Posted April 13, 2007 I believe it is so that if you remove the switch it kills the motor, otherwise the alternator will keep providing power to the load side of the switch and keep the motor running This is somewhat correct, but the main reason is that the when the battery is isolated with the alternator running, it will still keep producing an output but have no load (such as battery) to accept the current its producing. It ends up burning the diodes inside the alternator, and it will not work again. ie, time to get new alternator otherwise Dave Quote Link to comment Share on other sites More sharing options...
demuire Posted April 13, 2007 Report Share Posted April 13, 2007 Interesting... I've got my alternator on the "engine side" of the switch, and if I turn the switch off when the car's running, it cuts out. But I do see where you're coming from. Oh well, maybe next time I build a car... Quote Link to comment Share on other sites More sharing options...
BreakDave - GT Posted April 13, 2007 Report Share Posted April 13, 2007 Yeh it can depend on different things, like the car and how much electronics you got on it etc etc... ie carby/fuel injection 'but as a safe rule i'd put it on 'battery side' of isolator Similar thing can happen with alternator warning light circuit, where if there is no diode the alt will back feed through the ignition and can keep engine running wen u turn key off... hence why factory dashs have didoes built in. Theres bit more pointless info... lol... sorry to temporarily hijack the thread Quote Link to comment Share on other sites More sharing options...
Jono Posted April 13, 2007 Report Share Posted April 13, 2007 thanks for clearing it up! i wasn't exactly sure. Quote Link to comment Share on other sites More sharing options...
Wood§tok Posted April 15, 2007 Report Share Posted April 15, 2007 just remember, while running cables the length of your car, DO NOT connect it to the battery untill everything is all wired up and fused like a mofo. cheers. Quote Link to comment Share on other sites More sharing options...
trikesrule Posted April 15, 2007 Report Share Posted April 15, 2007 Coln72 said 'big ass cables'. Need to qualify that. Yes you will need big arse cables but what I think he meant is you will need high quality cables. Not the std crap that we all have. It's like when you fit a h/d stereo in your car. The wiring supplied is a far greater quality than the std radio crap. If in doubt see a auto electrician and get your wallet out. Running good leads is pricy. Is there someone here that can supply? Now if you want to get tricky at the same time fit twin batterys. U can have over 1000CCA for less weight than a single say 400CCA battery...........trikes Quote Link to comment Share on other sites More sharing options...
