Protek 9902AQ not functioning
The voltage reading is stuck in -8.6v and resistance range does not give the right value .I have checked most of the surrounding capacitor values ,resisters,diodes,and transistors but in vain .what could be the problem.

Try a new battery first. If not I’d recycle it and buy another.
