Bürstner 800i Electrical Issue

[ACB]

Hi, I'm having an issue with the cabin control panel not receiving power from the leisure battery (fully charged). The panel works fine when on EHU but no sign of life when not. I have checked the 50A/20A next to the batteries OK, I have pulled and tested all the fuses on the EBL220 and the Adapter box, I changed out 1 x 10A but that wasn't the culprit! Is there a mystery fuse box I wonder! Any advice would be appreciated.

Also have the i800.
Sorry can't give any answers, you seem to have checked the obvious. I once tried asking Burstner for a circuit diagram but no luck.

Are you certain that the leisure battery is fully charged and still has life? What you see when plugged in is the battery charger voltage. If the leisure battery is below a set point it will not turn the panel on

Sorry hit reply by mistake, I was going to add that a faulty battery will appear charged but have no capacity

Otherwise you will have to trace the wires to check for another fuse. Sometimes you also need to unplug and reset the panel

Have you checked the battery connections on the rear of the EBL220 , there may also be a 2 amp fuse near the leisure battery (living area battery sensor fuse)

Hi, thanks to all of the above. I checked the leisure batteries with a Multimeter and they are OK, I will continue troubleshooting.
