i use the solenoids also, wired into the ignition circuit. the set up i use is from Painless Wiring it's the MasterMinder series, for a few reasons...1. wires into ignition circuit, so when vehicle is Off the solenoids open thus, the batteries are seperated, when On the solenoid closes and the batteries are joined, for charging and also for power, if any one of the batteries are low, when joined gives enough amps to start rig. 2. this unit is run by a small microprocessor, charges first the main batt, then Aux 1 then Aux 2 and in addition inside the cab is a selector switch unit giving you the choice to use Main only Main and Aux 1, Main and Aux 2 or Emergency which joins all 3 together....Yes i said all 3! i run an Optima red top for Main, for starting ...Aux 1&2 are yellow tops, i use the second mounted underhood for additional other than stock electrics and the Aux 2 mounted in rear of truck for camping equip and Em back-up 3. the Masterminder also gives the option of installing a 110v circuit to plug in when vehicle is sitting for extended times w/o starting, i figure eventually i will add this for extreme cold weather charging if need be.
