solonoid choices , (dual batteries)

Post by bagsy »

Ive got a 93 GQ with the efi petrol 4.2 . Now im setting up the dual batteries but am trying to decide which solonoid to use. I was planning on just running the basic one , so when the cars on its charging both ,and so on. But i ve been told i need spike protection for the efi computer , therefore should i use a smart solonoid from arb which has inbuilt protection. Any opinions would be helpful. Also im running 2 starting batteries , just for winching. thanks shane....

So you're planning on running three batteries in total (the two off the starting circuit in parallel, plus another)?

What do you want to use the third for, as that can affect the options for a battery controller?

sorry for the misunderstanding, but no ,I only need 2 batteries . But they are both to be cranking ones because its mainly to run the winch. Do i need surge or spike protection for my efi computer ?, otherwise i will just run a standard solonoid. shane......

Fit a diode across the energise connections on the solinoid. This will cause the magnetic field to collapse into itself disapating the spike. Just fit it the correct way.... Or use a smart solinoid.....

You could just get two batteries that are exactly the same and hook them up in parallel if you're only going to use them for starting/ winching. But if you ever want to separate them at all, eg. use the second only for winching, then you'd need a controller.

Solenoids can cause current surges (and voltage spikes) when they switch in the second battery. The diode Dazz mentioned will only stop the reverse EMF on the solenoid's energising coil- not the spike from the contacts closing/ opening.

Dont buy the ARB one. You can get a Redarc one for $119rrp from http://www.ingram.com.au/ these work well.

buy a set of EFI jumper leads and a cheap solenoid. then you have isolation and spike protection.

You can actually buy small add on modules that supposedly do the spike suppression. You just wire them between the positive battery terminal and the chassis.

:roll: so you went and bought it anyway....
not sure if the ARB "smart' solenoid will handle the amps you intend pulling through it while winching....

How much did you end up paying for the ARB one?

Did you end up having to pay much more for cable and so forth?
This is not legal advice.

FYI, the only difference between the ARB and Redarc smart solenoid (solenoid unit assembled in Mexico) is the IC control unit that hangs off the side, and yes, the price.
The ARB unit worked quite well, until it failed in Cape York (warm beer).
Will see if the Redarc goes the distance.

This would probably happen on all soleniods though. Like starter solenoids, winch solenoids ect. Most EFI systems are fairly spike resistant .

i went with ARB isolator as well, for winch use only. the dealer recommend ARB over prahanas due to its ability to handle higher current draw.

No ive got a mate with the crimping gear and just needed a couple of meters of cable.

Dual battery setup

Post by hooters »

Best value for money at the moment is a VSR (voltage senstive relay) available over the net from www.tektrek.com.au
Just around $105 with spike protection and quality build.

redarc vs ARB

Post by 4x4family »

What is the big diff between the ARB and the Redarc, I've read on a couple of forums the bagging of each but what is the actuall difference, from somebody that knows about them

ive got a vsr.. the new ones are rated to 140Amps i think
came with cables, terminals ready to go
didnt have to fiddle with any alternator wiring either which makes installation easy

AFAIK they're both solenoid based with electronics controlling the switching of the solenoid contacts. Probably really not much difference between the two electrically, just the price.
