battery drain

[RAPP 1]

my battery keeps draining over night even though I switch everything off plus I've just bought a new 100ah battery and still it drains .
any suggestions please , as I feel it is the van because I've disconnected the battery all together on night and all was well I just cannot understand what has changed

Connect a multimeter in series to measure the current drain and go round switching off and disconnecting things and pulling fuses until you find it

What fridge do you have, has it been wired to run off 12v when stationary... IE: not running the engine.

Is it the leisure battery or the starter battery, or both?

Alarm/tracker? often the culprit.

If you are fitting new batteries, keep checking them after they are fitted. Maybe there is a fault which causes the drain.
For example, a faulty alternator diode will drain a starter battery, a faulty charger will drain a leisure battery.
