Electrical failure

[SID]

Any ideas on completely dead 2019 Ocean. No ignition, lights, horn, locks etc. Was working fine a couple of hours ago.
Any help gratefully received

So no electrics at all? Is the control panel display working? Have you looked at the battery connections? Earth?

Check battery terminals

I'd start at the battery and measure voltages along from there, following the wires. Measure from positive to the chassis. Post your measurements here in this sort of format:

From To Voltage ------ -------- --------------- Bat + Bat - xx.x Bat + Chassis xx.x Alt + Chassis xx.x ..... .....

Keep going until you get a reading below 11V or so.
