I had a brief look but couldn't see any wiring at all, and being honest a working seatbelt warning tell-tale is not high on my priority list, but I'm grateful for the pointer and I expect I'll find some time to look at it next weekend. There are a few elements like this that still require my attention, however, the results are overwhelmingly positive with the £36 repair improving the situation considerably.
Let's look at the results:
1 - No illumination of the fog light switch - Rear fog light still works
Result: The rear fog light continues to work but I now also have switch illumination, and when I press the switch its illumination goes brighter it indicate the light is on, I didn't have this feature before despite the fog light itself working just fine
2 - No illumination of the heated screen switch - Heated screen may not be working?
Result: I now have the switch illumination back, but I'm still unsure if the heated screen actually works? The switch illumination certainly does not go brighter when I put the heated screen on, I plan to test it next weekend with my infrared thermometer gun
3 - No indicator tell tales - Indicators still work
Result: Indicators remain working and both tell-tales have returned
4 - No headlight tell-tale - Headlights and sidelights still work
Result: Headlights and sidelights still work and the green tell-tale now works too
5 - No high beam tell tale - High beams still work
High beams still work and the blue tell-tale has returned
6 - No seat belt tell tale - This light never worked in my ownership
Result: As above, this still needs looking at, as pointed out by Doug it's probably just a broken wire or possibly something as simple as the connector is disconnected. Techniques Morgan would have had my seats out to fit the rear springs so perhaps they and those before them may have simply failed to connect the wires? Anyway, I'm not too stressed about it as I'm fully aware if I've put my belt on or not, and I always check to make sure my passengers are buckled in too.
Less positive is it does seem if I put the blower motor on its second high speed fuse 4 will blow, as we know this dash module fuse is rated at just 5a and I'm loathed to play about with higher value fuses again as this is likely to cause another board failure. However, disappoingtly since putting everything back together I now seem to have lost my hazzards, hopefully Richard can fix this when I can be bothered to pull the dash down again, at which point he can test the fan speed two relay and sort the heated screen if it proves not to be working.
So it's still a bit of a work in progress but I suspect some more upgraded diodes and maybe some more tracking bridges will fix these last few elements, overall while I still do not have 100% perfect functionality of everything I would still consider the very cost effective repair to be a great success.
I am also delighted to report since I put everything back together I seem to have inherited a free air conditioning upgrade! No compressor, no condenser, no trinary switch and no additional wiring was required... but out of the blue comes the never seen before icicle tell-tale when I put the heater fan switch to position one with the aircon switch on too
