Re: [Amateur-repairs] Precision test equipment

does it have a "soft" switch, or a switch that actually disconnects the
batteries?
if it has a soft switch, then check the switching electronics....usually
it's a resistor that needs to be changed in value, a leaky transistor can
do it too.
If it's not a soft switch, then see if there is an electrolytic cap across
the battery connections-if so, it may be leaky.
Check for this, even if it IS using a soft switch-some of them do this too.
Another thought:how clean is the PC board.....flux and other junk on the
board, mixed with moisture could cause the same problem.
