Probably port engine start and service, starboard engine start.

Isolate port and see if lights do not work, port engine dead.

Isolate starboard and repeat with starboard engine.

the reason I'm asking g is because one port battery is leisure but dead the other is 80amp car battery and the single starboard is another leisure.

Those batteries are incorrect if 2 batteries are to be linked in parallel they should be identical batteries & the single engine battery should be a start battery (car battery is fine) for your combined start / house battery you should idealy use a pair of identical dual purpose batteries that will take the start loads but also cope with slow discharge. Purely leisure batteries wont cope with starting loads & will fail early.
My previous boat had a similar set up for house batteries & I just used 3 x car start batteries I sold it 6 years on and the batteries were fine so if your not hard on your house bank then fitting 3 start (car) batteries will suffice

It seems i jumped to the wrong conclusion in my earlier post I assumed it was twin engine boat and should have 2 start batteries and a house bank
Looks like it has 1xstart 1xhouse which I'd imagine should be the leisure and the third for windlass and thruster
Apologies for my incorrect probably confusing post earlier
