Either my search mojo has failed, or this is as rare an occurrence as I think it is: but what I think of as the engine warning light (what FIAT lovingly describe as the "injection system failure" light) has stopped coming on, when I turn the ignition key. 
So, before I start taking the dash to pieces:

So, before I start taking the dash to pieces:
- Is there any obvious reason why this should happen -- apart from old age...? (I hate coincidences: but it seems amazingly coincidental to me (and a bit of a red herring) that this should happen just after changing the battery... -- especially as all the other warning lights, etc. still work fine....)
- Is this light soldered on; or is it easily replaceable -- once I've removed the cowl and dials, etc....? (If it's soldered on, I wonder if it's a dry joint? Problem is, my hands are now too shaky for such delicate work: so I'll have to find someone to replace it for me....)
- Where's the best place to obtain a replacement...? :idea:
