Not really mate - bugger-all. Normally have them disconnected anyway unless I’m camping/etc

A bit of an update
1. earlier in the thread it was mentioned how my set up didn’t have a yellow green wire, one was brown, connected tO top of sc80 as per Scott’s. I think the reason mine is different purely because Sniegy decided to install that way, Ie run brown wire to earth stud on car. The Traxide instructions indicate as per Scott’s.
2. I have had a switch installed. I took the car 5o an auto elecy to see if 5hey could identify the drain and install switch. They reckon the biggest drain was coming from the sc80. Based on testing so far thus seems to be true, I still have some more tests. The great thing about the switch is I can now split the batteries and see where drain is coming from.
With the switch off the main battery has maintained a constant value if 12.6v And the aux is at 12.8v, after a full recharge, for a few days so far. Never seen this before As it was typically dropping at .1v a day on both batteries.
At the moment the only thing running on the aux battery is the ABG25, not sure how much it uses but not much I think.
I do have to one more test but at 5he moment being able to turn sc80 off sure is a good option in my case

G'Day guys, i am going through this exact issue. Has anyone explored the fitting of a relay as well as the switch? The relay would bypass the switch once power was detected (presumably from an accessory feed), turn on the SC80 and charge both batteries whilst driving without the need to hit the switch. It would save the parasitic drain of the SC80 and ensure you are always charging, you would just flick the switch when you pulled up at a camp site etc to power the isolator whilst stationary.
Well that's the theory and i am keen as mustard to do it but have no idea what relay is required and the wiring diagram etc. If anyone has any pointers i would be extremely grateful.
A bit of an update
After having the switch installed for awhile now I do believe it is a good thing
My batteries still drain but no where near the rate when the sc80 was active
The one I can’t understand is why the aux battery is draining as it should have no draw on it other than the abg-25 unit. Not sure if ya can turn that one off with a switch but will look into it. I am not sure if this unit is effective in my set up. I understand it is supposed to turn off every thing On the aux battery once the battery is below a certain voltage for 3 days, I think, but prior to disabling the sc80 I found the batteries were draining to quick for this to be useful.
If the abg-25 is the cause of the drain on my aux battery perhaps removing it may be an option, has anyone done that.

Sounds promising. I got the following from Tim today and hooked it up, seems to work a treat. Now i can turn the isolator completely off but when i start my car it charges both my batteries, when i stop again the isolator is of until i flick the switch like when i am camping etc
Just get an ordinary Horn Relay and here are the pin connections.
Use your new switch in the earth wire to connect to the relay.
Go from the side of your new switch that is connected to earth, and wire this to pin 30 as well as pin 85.
From the other side of the switch, which will be coming from the SC80 ( Green/Yellow wire ) and connect to pin 87 as well.
Pin 86 has to be connected to a wire that is powered ONLY when the Ignition is on.
Here is the diagram of the horn relay.
