Warning: A switch mode power supply has primary and secondary
section. In order to check secondary voltage the meters black probe
have to connect to cold ground (chassis ground) and if you want to
test on the primary voltage, the black probe have to connect to
primary ground! If you are not familiar of what I am saying, please
ignore this test or get a repair friend to assist you.
