thinking about putting a second battery in the car

you don't need to connect it to the alternator.the way i described it is fine.both batteries get charged.
you can also put the kill switch in the cabin if you want too.just make sure you use good battery cable and terminals.
and also be careful where you run the cable to protect it from sharp edges etc.

well i mainly wanna connect it to the starter motor
i was going to have a look at 0 GAUGE wire would that be good enough ? were do you think i could get some of that?

you dont need to connect it to the starter motor.as the rear battery is connected to the front battery it is already connected to the starter motor.
0guage will be fine,try auto electricians,stereo installers etc.

I had one of these in my 4-bee DUAL BATTERY ISOLATOR ABR SIDEWINDER DBi120 *NEW MODEL* (eBay item 290521628267 end time 21-Jan-11 02:41:19 AEDST) : Cars, Bikes, Boats

worked a treat and was heaps cheaper than anything the shops were selling in town. It wont switch on till its getting above 13volts, which is generally after your car has started, so no drain on your main battery. Well worth $75 if you ask me...

I have some details of my Dual battery setup in here.

I used This isolator.
The setup is a piece of piss to install, about 2-3 hours depending how much trouble you have with running the wires.
Buy the isolator, and if you want the option to not run it all the time, grab a switch, then head to an auto-lec tell them you need x metres of Cable to run from starting battery to isolator and then to second battery for charging, I cant remeber what size it is. For the fridge sockets, run 4mm 15-20 amp wire, its over kill, but over kill is great.
Remember to fuse every socket you run off the battery and from as close to the battery as possible. The Isolator does not require a fuse.

Shoot me a PM if yu go down this way and got more questions.
