Hello all, I'm new to motorhoming having just bought a Hymermobil 534. It was imported from Germany so I'm having trouble working out how things work. Despite obtaining a copy of the Hymer manual, I can't work out how to use the leisure battery. The Battery 2 indicator is on zero despite charging it and there is no response from the interior lights, water pump or blow heater. The fuses all look fine and a couple of lights work when it's hooked up to the mains. I would be grateful for any guidance or help...... Thanking you in advance.
