On the hard shoulder...
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. :mad:

So, before I start taking the dash to pieces:

  1. 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....) :confused:
  2. 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....) :(
  3. Where's the best place to obtain a replacement...? :idea:
Thanks for your help; and any ideas/suggestions you may have.... (y)
 
Mine wasn't working either,
I've also had other electrical gremlins too.
But after taking the battery lead off for abit-following ziggys advice
Alls well again..

Bulbs are solderd in so iread somewhere,

Thanks! I thought I'd read this, too...! :eek:

Sadly, disconnecting the battery doesn't seem to have helped.... :bang:
 
Maplins is a good place for bulbs if you've got a branch close by.
I think the bulbs are s.m.d.'s
I'd try heating the solder up first as you say it might be just a dry solder joint.I think you may need a very fine soldering iron.

I'd personally not bother with checking for solder joints
I'd be just re-soldering them

Which im afraid Howard is not what you want to hear, since your fingers aren't upto it no more

I'd just use a multi-meter and see if there is even 12v at the SMD and if the SMD is providing a high resistance (blown)

You're all going to love this... -- I was so shocked, I didn't even go and get my iPhone from the house, to take a photo.... :spin:

At some stage in the past, either someone has had a problem causing the EML to come on, and 'cured' it by removing it; or it's simply failed to work, and then been replaced... -- but not very well. In fact, I'm amazed that it ever worked.... :rolleyes:

The problem wasn't a dry solder joint, but a dried out piece of Sellotape: holding the SMD (Sellotape Mounted Device) to the circuit board. It fell off, the moment I unclipped the board from the instrument cluster, never to be seen again. (I presume it had been held in by the pressure of the screen on the tape...?) I then spent a happy ten minutes cleaning off the sticky residue that the tape had left behind, with WD40. :eek:

As the car is going into the garage, next week, to have new suspension fitted, I shall get John, the owner (who also happens to be an auto electrician) to solder a new LED on.... :cool:

I've seen some bodges in my time, but this takes the Custard Cream.... :nono:
