Don’t see a fuse on mine. No brand name. New battery. Continuity buzzer not working. And, Voltages Both AC/DC) show . When n ot connected to a voltage. ? Nothing looks out of place. Looks clean inside. Only thing i can think of is trying to get to the switch. That doesn’t look easy. Printed circuit board has to be pryed out. Looks like. WAIT,ther does look like a place for a fuse. But,,nothing there. How didi it work,,at all. Have had it for about 13 years.
