Two steps forward, one step back
The non-functioning turn signal was nothing to do with the indicator light in the instrument binnacle. Unfortunately, I found this out only after removing the binnacle and having to trash a brand new lamp holder in the process…
The 308’s instruments are held in place with four bolts accessed through holes hidden behind the four coloured lamps you see in the corners. The holders for these lamps have an annoying habbit of breaking and becoming loose. All four of my originals were held together with electricians tape.
I needed to find some replacements that would not crack so easily but for the moment I was drawing a blank.
