My Uruguayan / Northern Ireland 29 Roadster came with an old Signalstat 900 Sigflare. It wasn't working of course, like most of the rest of the car!
I got it working, but the indicator lights failed on my last short drive out. I checked that the fuse was OK and 6v was getting to the unit. Then I took the unit off and dismantled it. Of course it would be easier to check the indicator bulbs first! When I eventually got round to that - all 4 bulbs were blown (6v / 5 W). Not sure why but I had one or two accidental 'shorts' when repairing my starter motor.
Anyhow, I took a few pictures of the dismantled Signalstat. It was quite heavily greased inside which I thought might lead to internal shorts so I wiped most of the grease out. I figured out that the hazard pull-out switch did work - it needs to be pulled out VERY firmly to click in place.
Despite trying several flasher units, none allow the indicator stalk light to repeat and it only 'clicks' once. The front and rear indicators work OK. On Hazard - every thing works normally, indicator stalk light and clicker. I assume 2 bulbs to left or right do not offer enough resistance load for the flasher unit.
From my internal exam - I would judge it very difficult for these units to fail internally. Can anyone roughly date it - ? 60's, 70's or maybe earlier?
