No indicators, speedometer or revometer

Hi guys, my srs light is always on now, and occasionally while i'm driving up, my indicators, revs and speedo stop working, the odometer doesnt even clock up the miles when this happens so im effectively making my gaylander worth more

on a more serious note i do a lot of motorway driving so for my indicators to suddenly switch off it is pretty dangerous..

any suggestions to the cause, however a couple of months back i used to get a shock on first touch of bodywork after driving, which i know means bad earth, but as i dont know where to look i ignored it, after a couple of weeks it then went away, after that this latest problem flared up. obviously linked i imagine seeing that are both electrical faults.

any auto electricians on this site who can offer a few pointers.

i did a search on the srs light here and have checked yellow wire under seat as suggested but to no avail.......

the shock yer gittin is static un got nuffink to do wiff yer fault [take orft yer nylon thunders] . . . .reet yer fault could be a poor earth connection or go into search it could be a wiring fault summit to do with the hill decent switch or summit, i carnt remember [look it up]its documented

thanks for your response fellow earthling but i have no hill descent switch. nothing on search for anything regarding my problems, perhaps an alien has been tampering with my freelander while im tucked up in bed....... that will explain the ufo sightings we've had.... ;-)
