Planning on putting a anderson cable/connection to the new van. i have a single battery vehicle.

Do i just put a VSR (like the $100 BEP one from BCF) in the line from the car battery to the van so that it breaks the circuit when the car is not running?

and do the cables run directly onto the terminals of the battery (via a fuse) in the van??? (doesn't effect battery charger etc)

Have read a lot of the archived threads on this site and looked at some of the wiring diags but just trying to get an idea how the connections are physically made.

You have it basically correct.

The VSR goes inline but always fuse at both batteries as the cables between batteries are always live .........as it is feeding from the alternator to Battery #2 with the alternator charging...and for up to a minute after engine shut down....then the VSR isolates but the cable is then carrying current from each battery to the VSR

Also be aware of the alternator voltage of your vehicle. In recent years the newer vehicles alternator charge at less than the 13.8V the VSR are programmed in at...There are now VSR to cater for the lower alternator voltage on the newer vehicles

just make sure you get the right one...it is a simple and foolproof method to use and very commonly in use

cheers

thanks bungarra, sounds like i will have a crack at it then. will put the meter on the car to see what she charges at.

so on the van side - from the anderson via a fuse straight onto the battery terminals????. there is a AC charger and a shunt on the van. should the negative cable go to the negative common rail???

IMO...you should go straight onto the battery terminals.........this allows for the charge received to "cycle" through the battery and there is no reason why it should cause any issues with the charger

Obviously the AC charger is not going to be charging the battery whilst the alternator is at the same time..and so it becomes irrelevant
