Outer Limits 4x4 Board

Hi all,
I was advised to do this upgrade when I installed a duel battery (ARB smart solenoid) system on my 60 series, is it recommended for my 99 desiel std van.
Cheers.

H Rough60, in all honesty, in Australia, the standard temperature compensated alternators are not all that advantages. There is some advantage but certainly not enough to go changing an alternator.

Cold climate countries benefit more from these so unless you are experiencing below 0c temperatures every morning when starting your beast, the advantages would be minimal.

Crudely put, how these work is that when the vehicle is cold, then the battery and alternator will also be cold ( Durr ) but because the battery is cold, it can take a higher voltage which in turn means it will take a higher current charge which all equals to quicker recharging after starting.

Once the motor is at operating temperature, the alternator is now going to be hotter and so presumably, is the battery. With the battery being hotter now, it should not be supplied with as high a voltage or it will be damaged and as the alternator has heated up and the temperature compensation has now caused the output voltage level to drop and, theory is, that this will prolong the battery’s life.

Again, great for cold climate countries, not all that advantages here, furthermore the temperature compensation is usually optimised to the characteristic of battery supplied with the vehicle when new.

The best thing to do is simply keep an eye on your present alternators voltage level and make sure it suites the battery you have.

Go to the battery manufacture’s web site to get the specific info for your battery.

Cheers

thanks for the info drivesafe
