In my Viz model WD-747 digital multimeter, the hot wire to the 9V battery broke off. Since the wire had oxidized and was impossible to properly solder back onto the terminal (even after filing the braided strands), I replaced the wires.
But upon opening the device, one wire popped off (see in attached pic the wire resting on the cover at right), which, looking at the connector at the end, is not soldered. I conducted a continuity test to see if the multimeter works with the disconnected wire: it does, but only for a short time. And it fails when attempting to read voltage.
I looked for a terminal on the circuit board inside the multimeter to which the wire might have been connected but see nothing that even resembles the lug at the end of the disconnected wire. I'm hoping someone might be able to help me find where the wire should be reconnected.
