Hi All, just bought a Camper king which came with a dead leisure battery. Once I uncovered the battery behind screwed in panels it had completely split open and leaked! See photo.. Anyway replaced it with a AGM battery and the lights work, nothing else is lighting up of the control panel but the heater seems to work even though it’s not lit up as on on the control panel.. i’ve checked every bladed fuse and all seem Okay.. Any ideas?? I’m think pulling the dreadful battery out has shorted something out.. thanks!
