T4 California Syncro control panel woes - tech advice needed!

[StevenP]

Hi has anyone got any experience of the overhead control panel ceasing to display leisure batt voltage? Mine has worked fine although I don’t have the bar chart section since replacing a burnt out charger with a Victron, but suddenly stopped, and now wont allow the fridge or heater to be switched on as it thinks the battery is dead (it isn’t ) - any ideas? Thanks Steve

PS any contacts in the trade for Cali electrics also much appreciated in case I need a pro!
