Submersible pump not working

[Old Jabez]

12volt electrics is a dark art. My submersible water pump has suddenly stopped working in my Transporter 6.1 conversion. No power is coming out of the control panel ( see image) to drive the impeller. Pump power switch doesn’t appear to work. Pump, however, works fine in direct test to battery. Tap micro switch showing that’s it is working on meter. Having established both tap and pump seem to okay, I’ve changed the control panel. New unit: Problem still exists, with the added issue that the tap when in the on position turns off the internal lights. Crazy. Any clues?

Where are the fuses, have you checked them?

Thanks for responding. Yes, checked fuses. All okay. Conversion builders AVT in Tewksbury now on the case. Hooding for a solution soon.
