Hi,

I have a Metex M-3650CR Multimeter and I have recently changed the fuse out, but when I opened up the case the wires for the battery and speaker broke, I have fixed the battery wires and it turns on now, but I am going to leave the speaker not connected.

Anyway, when I turned it back on the screen displayed OL (Overload), even when their was nothing connected, I tried testing a AA battery but still nothing.

I turned the dial round and it said overload for every mode.

What could be the problem? I have verified that the fuse is correct.

Thank you in advance
