Hey everyone,
I got an older device here I am repairing. The previous owner tried to replace the solder type battery and seem to have lifted the pad to the negative side of the battery terminal. It uses a 3.7v lithium battery for the SRAM. The SRAM contents aren't saved when power cycling, so i went to check the battery voltage and it was reading 3.5, so that is no problem. I then inspected on the other side of the PCB and found the lifted pad.
The track from the negative side of the battery seems to lead to one side of a 2N4401 transistor "Q7"
Do you guys think I could tie a wire between the battery leg and transistor leg? I know to be very careful with heat on the battery leg.
Normally i would try without asking but since a battery is involved, i don't want to cause a problem.
Thanks everyone
