Can someone help me ID these components?



These seem to be dropping the voltage from a rechargeable NiCad battery in a Fluke meter.  These are the first components that the battery grounds see between the battery and the rest of the board.

    



Any ideas?  The look like they took some kind of hit.  They fell off when I touched the wire with a probe. The long end of the lead seemed to be melted off its junction with the PC board.  One of the little cubes left part of itself attached to the board.

  



I don't see any markings on either one, but they're tiny so I may be missing it.



  

Sure would like to make this meter work on the battery--works fine with the wall charger.

Photos attached, one for detail, one for scale.

Thanks!

   Nothing I recognize. I did get your 'tingling wall wart'.

   I'll go out to the lab tomorrow and see what I can

   find with it.



   What model Fluke are we talking about?

123 Scopemeter



The battery has 4 leads.  I assume two are for temp sense.  Those little guys come one each off of battery (-) and one of the presumed temp wires.

Thanks, I'd like to know more about the charger too.  FWIW these are unrelated.

David,

  

 I suspect they are "surface mounted" components that  should not be free from the circuit board.  They could be resistance or  capacitance devices.
