indicators was working until i took the nearside front indicator out of the car then they all went out i found a blown fuse? i changed it, they worked again for 5 seconds and all went out again . this time there is no blown fuse so i found a relay diagram on here it shown relay 8 to be the suspect the big black one? so i have one these off a written off 320 i stripped for spares a while back i changed that still no life and they also dont flash when alarm is pressed can anyone shed any light on this???? thanks alot Dan
