Thread: Separating starting and accessories circuits?

Traxide SC40 Smart charger isolates your second battery for accessories, I have all my accessories running from my second battery, being looked after by my SC40 for 5yrs now.

EDIT; it's a plug and play device, set and forget, can't get any simplier

But it seems there's only one power input to the fuse box - which could come from the 2nd battery but this also then provides power to the ignition circuit, so if the 2nd battery is flat you still can't start the car?

My Pirahna has the display/control unit inside the vehicle. It allows linking of the batteries. I have used this feature once some years ago when the main battery was at end-of-life and did not have enough grunt to turn the engine. The charging circuit is automatic for both batteries, with a voltage display on the press of a button.

It has been trouble-free, worth considering.

I can (or will be able to) override the separator so both batteries are linked but I was trying to work out if it was at all possible to keep the starting battery purely for starting, nothing else, and have all other power requirements taken care of by the auxilliary. I think I've answered my own question in that even if it is possible it would be so complicated (read expensive) it's not going to be worth it

cheers, Andy

G'day,
Just for clarification are we talking about a 2 Batt. system? ie. original fit, what Landy?

Seems most replies are for duel batt. set up. ie.Owner added.


Cheers, Kyle.

Good point, I should have been more specific. It's a D2a TD5 so only one original battery, 2nd one added by me.

cheers, Andy

If it has a Pirahna system fitted the wire at the fuse box(Under dash) is for voltage input to link batts. when motor running.(Won't put power to fuse box)
If fitted corectly anything that works off the 2nd. batt. should not drain the start batt. ie.Fridges,camp lights ect..

What "separator" are you thinking of using?

There is a thread some where on set up options.

Cheers, Kyle.

Gday Andy, When you have the second battery all the original 12v sockets i.e cigarette lighter and the 1 in the cargo area are still connected to the main battery and should loose power when the Acc is OFF on the Key barrell.
You need to run a new 12v socket drawing power from the 2nd battery then use this for the fridge ctc, then if you have any radios( UHF ) or camp lights etc wire them to the 2nd battery.This will mean that only the original accessories that came with the car will draw power from the main battery..Most battery isolaters will isolate the main battery once the ignition is turned OFF and the main battrey Voltage drops to a set voltage, then all power comes from the second battery.You can get manually operated switches so you can use either battery or link both if needed, but most of the good electronic ones have this option. Im not an Auto lecky but to totally isolate the electical system to a different battery and use the main battery to supply the starter motor would proberly cost more than the car did.
From how I read your post I think this is what you were asking..There is a tutorial that shows someone fitting new 12v socket in the rear cargo area, im just not sure which 1, could be one of the dual battery posts.
Hope this helps..
Cheers Ean
