41CV won't turn on after reassembly. Did I kill it?

Still nothing so far. I tried pumping a 6 V supply directly into the battery terminals via alligator clips, and I could see about 12 mA standby current (seems a bit high), but nothing happens when I press the power key. I noticed that the springs in the battery holder had a tiny bit of corrosion/oxidation on them, so I coated the two that looked bad with a bit of foil, and I was measuring much better series voltage from each pair of cells after doing that - much closer to the actual sum of the voltages from the individual cells. I've got fresh Ns coming in the mail tomorrow, so I'll see what happens with those, but I'm not expecting miracles.
