Display horn and fuel gauge not working

[Sparticus]

Hi all
New here.
I’ve bought my son a 50cc super 8 that’s been off the road a while.
Just working way through bike and now I’ve got it running sweet I’ve noticed the horn display and fuel gauge are not working.
I’ve checked the inline fuses and the lcd is back lit.

Any help appreciated.

Fuel float pcb was broke
Ordered new.

No idea on clock and horn yet though
