I know that this has probably been posted on here a million times but i cant seem to find it anywhere.

I would like just an easy-to-follow guide or wiring diagram for setup up a proper secondary battery system.

Thanks all.

Put second battery in the boot and speak to piranha 4x4 or an agent in your area for in my opinion the best battery isolation systen. They have various systems for different aplications to suit your needs. You can install your self but I am not sure how comprehensive the instructions are.

Redarc make a Smart solenoid which is very easy to wire up.One wire from the start [original] battery positive to 1 side of the solenoid and the other side of the sol to the 2nd battery and the negative battery terminal to earth.Depending on the size of the cable you use you can jumpstart from the 2nd battery and if you are using 8b&s or smaller you will need to fit some circuit breakers to protect the system.Cheers Kevman.

yeah im going to have a go with the Redarc Solenoids. They seem to be the way to go.

Cheers for that
