Check yer earths Gary..........all nice and clean and together as should be? You'll know this but they'll flash like crazy if there's a bulb/connection incomplete somewhere, are they all working? How bad is the flasher unit, is it in reasonable nick?Might be the switch but check those bits first is where I'd start.Flasher looks and sounds good, Im off to recheck earths, switch should be good every thing worked when I bought it. Could it be DS indicators?
Can I enquire as to whether that part specific to the 500 models only as my 77 550 F2 doesn’t have one. Unless it’s a parts manual oversight/error and I can’t remember removing one.
