156 main beam indicator
Thought I had a blown bulb on the main beam telltale on the rev counter of my 03 156 2.0 JTS.
Only now I've replaced the bulb, the telltale (by which I mean the blue light that indicates that main beam is on) still doesn't light up, although the headlights themselves are working fine.
When I swapped the bulb and its twist-out holder with one of the other two at the back of the rev counter (the ones that provide the backlight), the fault stayed where it was - so, not the bulb or the holder but presumably something blown in the circuitry between the main beam switch and the main beam telltale.
Main beam fuses are fine (and if they weren't, the headlights wouldn't be working) - so I assume logical next step is to replace the circuitboard behind the rev counter - or more likely the whole unit.
Anyone got any better ideas?
