check your alternator you may find that it has a second output which is isolated from the one that currently charges your batteries. IF it does just plumb the second battery up to that and you're set.

Hi Andrew I have one of the electronic controllers think it cost me around $100.00 it has worked really well for 3 years now and been fitted to two different vehicles. It is simple to wire in requires one wire to + on main battery and one wire to + on the aux battery the - on the aux batt then goes to the nearest suitable earth.
Would reccomend when you tidy up around your battery get rid of all the crimp terminals and use a soldering iron with heat shrink for insulation of any joins or live terminals.
Send you a few pics of mine if you like.
Andrew
crimp terminals done with a proper crimping tool can give you much better service in a world filled with vibration than a soldered fitting...
each has their place IF done correctly....
I've crimped, then soldered, then heatshrunk all my connections.:DQuote:

Another problem with operating the solenoid directly from the ignition is that it can mask the condition of the main battery. When the main battery is reaching the end of it useful life it will have enough capacity to operate the solenoid when the ignition is turned on but may not be able to deliver enough current to crank the engine. The aux battery will be supplying the cranking current. This will not become evident until the aux battery has been used to supply an aux load while it is isolated from the main. If the aux battery voltage has dropped too low you will find yourself with two flat batteries.
So, not just a "belt and braces" man then.Quote:

Job done
Ended up going with a BEP Marine - Voltage Sensative Relay
Cleanup the wiring as well..
looks neat
I had a similar problem when I had the solenoid in my Rangie.Quote:
