89 autosleeper. what does leisure battery power?

[Sir Brixalot]

Hi all. Camped without hookup last night and noticed that everything seems to be powered from the main battery. Can anyone advise me what the leisure battery is meant to feed. Thanks

My auto sleeper has all camping stuff on the leisure battery, lights, water pump, fridge on 12v needs the ignition on though. Radio and door lights are on starter battery.

My sleeper
Aux batt :- fridge ignition, water pump, water level meter and battery meter. Hella 12v socket. Clock, radio, propex heater (now webasto) rear cabin lights (except the one over the slider) and the spotlamp.

Thanks for your replies. Think the kids had been fiddling with my headlights and left them on and I jumped to the wrong conclusion.
