Electrical fault!?

Problems happen at the weirdest times for me. It usually happens when I make a quick stop at the store. Everythings normal on the way there. I come back out to the Rangie and there it is! ELECTRICAL FAULT! Nothing seems too far out of the norm, except blinkers don't make noise when turned on. Usual dash beeps are gone. It does say LH-F Door open. Interior lights don't come on when door is open. And also headlights come on when started even when they are selected to off. Anyone have this happen top them? Any tips on where I should start? Thanks guys

check the earth lead on the battery, if you can wiggle it tap it down and tighten it up.

Okay. Thanks Gav. It just seems that right when I think everythings sorted out...something else randomly happens. I guess thats just what comes along with being a RR owner

things like this are usually down to poor connections on power side or becm under drivers seat!
