ARB Smart solenoid/ emergency starting??

Thanks mate- I think you're on the right track there..
Cheers

Hi Tony...
Why would the 'centre' pin (next to the grounded one) be going to the starter motor??..
See my current set up below..
Have you any suggestions for a recommended wiring setup??

It is wired to the starter because when you start, it overrides the normal function and closes like a relay.

Mine was set up like this and it was bad because I had a flat main battery for a while and didnt know it bacuase the car started ok from the Aux.

The way I have it wared now is to put a switch in the middle of the line to the starter. Taht way it normaly starts of the one battery ( cranking batt) but you can over ride it when your cranking batt is low it is like jumper leads between the 2 batteries.

Thanks Coyote- yup it was a bit confusing (I am a bit slow)..
Any how- the 2 fat cables are where they should be..
Now the spade connectors..(currently on my vehicle).
The one closest to the mounting bracket goes to earth (body)..
The centre one is wired down onto the starter motor..
And the 3rd (closest to the bigger connections) is empty
Any ideas from yourself (or anyone??)

I have no idea why the centre one is wired to your starter motor. Mine is not used at all. My earth is the same as yours.. (closest to mounting bracket) and the one furthest away goes to my switch (these two spades are parallel to each other and the middle one is perpendicular and not used)
Then I have a positive cable coming from the "fat" cable connection at the solinoid that runs to the Aux battery. this + cable also goes to my switch.

This set up basiclly overrides the solenoid which is designed to seperate the batteries when the engine is not running (ie prevent any power drain on your cranking battery when stopped) you should be able to here the solenoid click when you turn the ignition key. This solenoid also makes sure thast the cranking battery recieves all charge from your alternator before allowing charge to flow to your aux battery.. otherwise like some of the cheaper solenoids all that happends is that the batterys just even themselves out. (a bit like to buckets of water with a hose between them.. if you don't have a "smart' valve between them,. they will just become levle with each other resulting in possibly 2 batteries (buckets) with out enough power to start anyway.. thats why the "smart" solenoid is so good.

Just had a squizz at the SurePower details...
Apparently- the wire from the centre pin to the 'starter motor' is in fact )indirectly) connected to the start position of ignition. It is supposedly for 'automatic operation'.
I don't think it's very 'automatic' as I did have a cranking battery failure (after leaving headlights on) and it didn't work.
It looks as if you've gotta have at least 3V for it to actuate- so my battery must have been dead flat.
Think I might put the 'manual' system in..
Thanks for your assistance..

Hey Coyote
Just to confuse the issue for you..
The diagram on the SurePower site shows the CENTRE spade is for the Auxilliary start operation.
The spade opposite the EARTH one (closest to the big lugs) is for the 'Auxilliary Start Indicator Light'.

maybe mine is a different model or is incorrectly installed by ARB.. either way, it weems to be working OK and I'm not going to muk with it.. I have found out the hard way that tampering with a professional installation usually ends up in tears.. Cheers..
