Does anyone have one of these. Mine has been disconnected and had the wiring removed and the wiring diagram has rubbed off. I have no idea on the control circuit now.
A picture of the front of one would be great as the manufacturers website is as usless as mamarys on a male cow.

Sure power industries (ARB) dual battery isolators

Stand the unit up on its mounting feet.
The spade terminal at the bottom requires a small earth wire.
The spade terminal in the middle is for the start assist function, connect this to your starter motor cranking signal wire.
The top spade terminal is an output for a dash light - to tell you the start assist is feature is being used (no real point to connecting this, normally left blank)
The two main battery connections are obviously for the main and aux battery. I am 90% sure that the terminal closest to the plastic body is the aux, and the other one is main. If you get these wrong it just wont join the batteries (as it thinks the main battery isnt being charged) Simply swap them round if it doesn't join the batteries once the engines running, it cant cause any damage.
I can get you the instructions tomorrow if you like?

spot on thanks mate. I can see teh terminals for the battery cables, just not the control. I will hook it up tomorow.Cossie wrote:Stand the unit up on its mounting feet.

What is the start assist feature??
start assist brings in the 2nd battery to assist with starting. I believe it only does it if the voltage in the main drops below a certain level.
The theory is that if your main battery is a little low (headlights or radio left on etc) you can still start the car without jump leads.
In reality it always brings in the 2nd battery when cranking, then seperates it again once started. Then when the voltage in the main is over about 13.5 it joins the batteries, allowing the 2nd to charge.
Then when the engine is off and the voltage in the batteries drops to 12.5 it seperates them again.
The downside of start assist is that it can disguise a failing main battery until it is too late.
If you choose not to use start assist just run an earth to the lower spade terminal and leave the other 2 blank.

The other option is to run a switch in the line of the start assist. Then when it is in the off position it will always only start on the main battery, but if the main battery is a little doughy or wont start the car, then you can switch it on and it will function via voltage and bring in the second battery like normal to assist start up.
