This diagram may or may not be relevant to your particular vehicle. If not, sorry!

If you have more relays/fuses higher than shown on your picture, I'd be checking P030/P031 and possibly T23.

Hi slidder,

You second picture shows Optional Fuse & Relay Panel 1, together with optional Converters Sockets. The supply for the power socket is taken from a dedicated 50A midi fuse (3) on the battery fuse panel. I am wondering whether the relay panel is also connected to this supply?
