Stagea light problem

[gerry whtie]

Recently had a battery failure on my M35 and after an unsuccessful attempt at jump starting when a new battery was fitted i found my speedo/tacho dash light wasn't working, neither are

my indicator repeaters in the same dash, the reversing light audible warning is not working as is the door open with ignition key in audible warning also not working. Ivé checked all fuses in the 3 fuse boxes finding one blown which made no difference when replaced, has anybody got any suggestions as to what the problem could be as i'm no auto electrician.
