Hi,
I have a rotronics 3ST12CFV in a prado I bought recently.
I was wandering if you can change to the Aux battery if your main one goes flat so I can start the car. As I have no idea if it is possibe or not.
At the moment I use jumper leads from one to the other to start it.
All help is appreciated
Cheers, Dan

you're on to it. I used to carry a small 10mm2 link cable with 2 lugs, a couple of m6 nuts and a 10mm spanner. there is no switch/easy way to do it.

Assuming they haven't changed their functionality no you can't
bridge the batteries for starting.
You can select to charge aux, and top up main, or charge main and aux,
or main only.
You could install a separate solenoid to
bridge the batteries or a battery
coupling switch.
Being practical, with the Rotronics installed you should never flatten the main,
if you should by accident then just jump with cable.

I understand that, But I have electric rust control on the vehicle and I only use it every fortnight. So the only way is a jumper lead or a solinod switch.
How would you wire one in.
Is it possible for you to send a wiring diagram

In that case why not buy a 7 Amp CTek battery charger and leave it permanently connected when the vehicle is idle.
I haven't driven my Troopy for about 3 weeks but I do know it will start first kick when I next jump in it and the battery won't be dstroyed by continuously running it flat.
I usea10 Amp CTek on
mine but a 7 Amp will do just as good a job.

Agree with Geoff, if you keep letting your battery run down and leave it in a discharged state it is only going to ruin the battery.
Solenoid option would be expensive as you need a solenoid that can switch around at least 400A to crank the motor.
