Hey, I've got a Triplet DC Volts panel meter, model 327-A, 0-200, that I thought I would use for a dopey little steampunk type amp. I took it apart, very carefully, and cleaned up the plastic and glass. Put it back together and touched a 1.5 volt AA to it and it wants to slam over to the right. I feel sure I was careful when I disassembled it. Any thoughts.
