Just my overpriced $0.02...
 
It's probably best to put it back together the way it was intended.
 
After upgrading my FMR I had similar problems, that metal plate on the
inside at the top of the player would move and cut the power.
Ultimately I readjusted the plate (put a little more bend into it) and
retightened the tiny screw (above and between the two LEDs) holding it
down and all's well.
 
IMO Soldering to a battery wouldn't be easy, it's a nice heat sink so
you'll probably end up with a cold solder joint and worse yet, the
solder might not adhere to the battery and end up bouncing around the
inside of the player. Also, the player can only put up with as much
vibration as the hard drive can handle, so IMO there's no point in
making a bulletproof connection, the compression type connection they
currently use should be fine, just tighten it up.
 
One thing to think about... If your player is bouncing around while
you're riding yor bike and causing the batteries to lose contact,
imagine what that vibration would do to the read head on your hard
drive. One good bounce during a read cycle will crash the head and
break the drive.
 
Best of luck!

        Subject: hardware 'mod' for FM's
        
        
        Hello all,
         
        I recently announced that I fixed my Fm recorder due to the
badly designed grounding/negetive plate from thebattery to the casing..
Well it's still not perfect and switches off on accassions (when on my
bike and stuff). So I am considering solderiung the negative of the
batteries directly to the ground on the motherboard. Is this a bad idea?
Can I damage the batteries by soldering directly onto the end? All I
want is a good contact that lasts, and it's currently unreliable. If I
ever have to change the batteries, I can just desolder.
         
        Any help/ideas, most appreciated!
         
        mat
