G'day all,
I'm after some info about the Redarc solenoid please. A bloke at work has asked me how he can override the contoller in the case of having a flat MAIN battery (as happened to him once already on his V6 Prado because he was watching the footy all day with the radio on).
The Redarc has a loose wire on marked "Over-ride" (I think....or something like that). I said I assumed that he would need to connect that wire to a know good 12v source (eg: the 2nd battery in his case) and that that would trigger the solenoid.
Was I on the right track?
Thanks
Roachie

Short answer, yes.
That wire can be run through to a momentary switch, connected to the second battery. Push the button, solenoid "connects" both batteries, turn the ignition key and hopefully you have enough charge in the second battery to start.

Bill,
Also works by putting a screwdriver (or something metal) across the two contact points on the isolator.

12v Jumper lead works good.

If you do the screw driver trick make sure you have all the electronics disconnected, it can cause a huge spike.

That's exactly how it works. I have a momentary switch wired to that wire just for that scenario. Have had to use it once and it works great.
Only proviso is that your wiring must be capable of handling start current...

I use these 15 Amp jumper leads to connect the Cranking battery to the AGM's @ the Rotronics battery isolator, so Cranker will also be charged direct by the Solar system.

Would require larger capacity clamps, can be stored safely by clamping to something in the vicinity and used for any battery to battery charging.

You can also do as I have an wire a relay in so that when u turn the key it uses both batteries to start the vehicle. As per TD Cruisers. Just I'm lazy and cant be bothered looking for the pusbutton.

Roachie,
I also believe that it does not require a full 12v to activate. therefore would not matter whether main or aux battery, from memory only needs something like 4v

Hi Roachie
I have a drawing for this which also includes how to fit the remote LED.
Email me for a copy.
