Hello I have a 1996 Hymer B644. I have just had the wheel bearings done and on my return i checked the control panel. The indicator for the leisure battery was working but the 'Test Batterie 1' for the starter battery didn't move. I have an Electroblok 104-2. Is this a fuse problem? If so, where is the fuse ? Is there a right or wrong way to replace the fuse (turn things off for example before changing the fuse). I am new to this but one thought was that the mechanics might have left the key in the ignition in order to maneuver the wheels (they had it in over the weekend). However, it started up fine when I picked it up. Any ideas?
