Hi all, I have an FM2 that has never missed a beat since i bought it 20 yrs ago. Also I just bought an FE2 off ebay in practically mint condition and just this week BOTH of them have started up with the EXACT same problem: the meter functions intermittently. FYI: 1. the batteries are brand new energizers out of the packet (I have tried several sets from different shops). 2. there is no visible corrosion in the contacts or chamber (i cleaned them anyway) Sometimes all is well and working, and then ... suddenly: dead. just when I think I am losing my mind - they work again! Anyone had this problem and know a solution?? can I dismantle/clean/fix this myself somehow? Thanks in advance for your help!
