This morning the offside indicator decided not to work

took off the lens and the rubber boot has split open so the bulb holder terminals are almost rusted to nothing
I've ordered new bulb holders for both sides as no doubt the other side is the same

I'm hoping thats all the problem is

but as the side light is flashing instead of the indicator I suspect your all going to tell me this is a bad earth somewhere
So while I'm waiting for new bulb holders to arrive where and what should I be looking at just in case its not just the rusty terminals
Cheers
Steve
