Right having problems guys need some help! I've put a new loom into my erst s2. Can not get main beam to work at tall wen u go to switch it on to main main beam he lights turn them self off.

I've checked loads of things. The one most unusual thing is that there seems to be a constant live up to the switch from the relay? From the Main beam wire which I believe is a white one. but only from one wire not two? What I mean is there's not even two lots of main beam power from the two diffenerent sources. and should the one always be continually live?

Any suggestions on this would be greatly appriecated!

Cheers
