The split charge system should stop current flowing from the cranking battery to the leisure side when the engine's off or the cranking battery's low. Shouldn't have to manually disconnect it. If your alternator is undersized and the fridge is way above target temperature, there might not be enough left to charge the leisure battery.

Yep, that's all stuff I know :)
Is there any reason having the cooler on while the leisure battery is charging (from the alternator, no mains for now) would cause issues? Then just disconnect from the starter when the engine's off and let it run off leisure?
No plans to run it all the time, only after a big fresh food shop and when we need to keep beers cool for half a day or so...
