Hi L, best if you can unplug everything but usually miss something or can't get at it so,
at board disconnect lives & Neutrals for your circuit and put them together temp. then test all 4 to earth, at same time. Reading should then not be affected by anything still in circuit, also you won't hurt anything connected.
you should then get good reading, if OK test L to E. (N clear of earth contact), should be OK , then do same for N (L clear of earth contact).
If all ok try continuity of L_N on OHMS scale not M ohms if reading anything then something still connected, may be Neon on FCU?
