cheers guys it was a earth problem but i have had to add anther earth wire to the indicator because i can't find the problem.

theres 2 earth wire's coming out the main loom near the o/s headlight but they are earthed ok, i've even put an earth wire from the battery to both earth wires and still won't make the indicator work.
so i've had to add another earth close to the indicator which also earths the side repeater.
there must be a break in the wire somewhere?
