Picked up this multimeter known to be not working

Had no display whatsoever

Opened it up.  No battery 

Installed new battery....only display on certain modes.   

Checked internal $30 fuse.  Open 

Installed new fuse.  Fingers crossed.  No change 

Connected mini-grabbers and 150 ohm resistor

Continuity mode.  Nothing

I would see if you can verify switch contacts for bad ranges/functions.

Agree with G1.  I had a similar issue to a meter.  The dial is connected to a circular metallic gizmo that turns and makes connections to points on a circuit board.  That metallic gizmo was dirty and had slightly deformed.  So I bent it here, bent it there, reassembled and voila, the meter and functions came back to life.  Make sure you also use some spray cleaner on all contacts and pots.
