Howdy folks, hows things?

Just a quick question if I may...

I have just purchasedan 80 series 1hz diesel Cruiser which has the dual batteries already set up. It has the VSR (Voltage sensitive Relay module) in it. I am aware that this enables the spare batt to charge up the main batt when it gets low.

So, is this totally self monitoring? was this standard across the 80 series range? (as there is alot of fotos in manual with dual batt). Good unit?

I am about to head to north WA, so tryn to get more familiar with how it works....

Cheers

Rowen, you say: "I am aware that this enables the spare batt to charge up the main batt when it gets low"

The VSR does N0T enable the spare battery to charge up the main battery when it (or any battery) gets low!!

Hi Rowen

To answer your questions.

1) The LC80 did not have VSR's fitted as standard.
2) VSR are normally connected to the main battery and when the main battery is charging at approx 13.5V or greater it will then energize and charge the aux battery. Once the main battery drops below approx 12.5V or the engine is switched off the VSR should open allowing the accessories to run off the aux battery without draining the main battery.
3) Some but not all VSR's will have a jump start option that will allow you to start the engine off the aux battery if the main battery is flat.
4) VSR's are automatic but it is best to also have a battery monitor fitted so you know the status of the system.
