My indicators have stopped working but hazzards ok. With help from the forum got the relay out and dismantled it. There are 2 sealed relay units on a circuit board. All the suppliers of complete unit are out of stock so have ordered some spare relay modules from Mouser (only £2 but postage £12!) and will try to repair the unit by soldering replacements onto the board. If anyone knows where i can buy a complete unit please get in touch.
