Step 8Adjusting the VSR and installing the batteries
Nearly there now.
Reconnect you starter battery by first connecting the the +ve battery clamp and then the -ve battery clamp.
Install both the 25 amp fuses.
Now check the correct operation of the VSR with a multimeter. You can do this be sticking the +ve probe of you meter onto the leisure battery end of the long red charge cable.and touching the -ve probe to the van chassis. There should no voltage.
Start you engines!
Now measure the voltage at the same point. If the VSR has made you should read about 14v on your meter.
If you don't detect a voltage one of three things has happened.
1) There is a problem with your circuit. Check anything for faults.
2) Your starter battery is very flat and pulling down the input voltage to the VSR below the trigger threshold. This is pretty unlikely since you just started the van which would imply the starter battery is in good shape.
3) The trigger threshold is set too high and needs adjusting to the correct level. Stick a small flat bladed screwdriver in the adjustment hole on the VSR and turn the pot until you hear a click or measure the 14 v with you meter.
Once this is done you should check that the VSR turns off when the engine has stopped. Turn the engine off and measure the voltage again. You will most likely find that the voltage will drop off slowly and so the VSR will not unmake straight away. This is expected. If it doesn't unmake after 30 sec to a minute then the threshold needs tweaking down a bit until you don't see a voltage.
You may have to go round this loop of starting the engine, measuring, adjusting, stopping the engine, measuring and adjusting a couple of times before you get it right. Just don't be too quick to adjust it down, allow the voltage to slope off first.
Now all you need to do is drop in the leisure battery in. For safely remove the fuse from the starter battery end first. Now connect the charge cable to the +ve leisure battery clamp and the clamp to the +ve post of the leisure battery. Finish off by connecting the -ve leisure battery strap to the -ve leisure battery post and reinstalling the starter battery fuse.
Job's a gooden!
Wiring up your electrical goodies is a job for another day.
Put you feet up and crack open a cold one.
