Hello,
I had been having a recurring problem with a model WV-38A RCA VOM that I
built from a kit way back in the day. For resistance measurements it
uses 4 AA cells and 1 D cell. Over the last couple of years sometimes
it worked fine and at other times the meter wouldn\'t budge, regardless
if voltage, current or resistance was to be measured. I couldn\'t find
anything amiss either- no blown fuse, broken circuit board traces or
faulty or oxidized wafer switch contacts. I spotted some green
(apparently conducting) material on a circuit board trace near a battery
holder that had also migrated to other parts of the board. I think the
material came from a leaky battery. I cleaned it off with rubbing
alcohol and the VOM once again seems to be working reliably. Has anyone
had a similar problem? Thanks for your time and comment. Sincerely,
