Thanks for the reply. There were four ground wires in the loom and two had continuity to the existing indicator ground so I just picked one of those to use. Do you think this is where it has gone wrong? I need to pick the other ground that had continuity to the indicator ground?

Chances are that earth is not a earth if you turn your lights on you will probably find your earth has power to it ( using a test light of course. ) . When your lights are off there is enough resistance through your headlamp globes to earth and enable your indicators to light up. When lights are on you have 2 positives and no earth (negative ).

run earths to chassis , or earth point on body or engine

Thanks guys - looks like I'll need to get back in there again and have another look.

Cheers, Josh
