The 12v supply for instruments in the pilothouse (VHF,AIS,Windinstr.,and engineroom monitor) has been a mess. It was organised and rebuilt. A new Victron Multi Inverter/charger with new multicontrol was installed (the old one with 19 years on it is working flawless but has a software to old to communicate with any modern electronics !?) and the aircon unit 1 for saloon and pilothouse had a burned capacitor on the fan unit which was replaced and now up working.
