The plot thickens.

To my disappointment it turns out it wasn't the relay at fault, replacement turned up today and fitted, however problem still exists. Which is annoying.

Does anyone have any idea's what the cause of this could be? The switch is good and solid, tested with a multi meter today just to be sure and all is good with the switch. Relay is in good working order.

Another this is that i've noticed the indicators will work as normal at low speed (I.E under 10/15mph) if this helps at all.
