re 1) try to reverse the battery.

Both of my Electros (original silver and a GT) show the behaviour that the battery test light only works if the battery is inserted the wrong way, the exposure meter only works if I flip the battery around...do not ask...maybe thats because of the adapter, or the different battery or something else...

2) try putting your finger in front of the smaller window (not the one with the mini aperture, thats the CdS meter) and look through. It COULD be that some mirror is missing, but I doubt it.
3) the shutter fires even with the pad of death being death. Its just not as accurate any more.
