cause a pcboard to fail?
PCboards fail because of power outages, surges,
and brownouts. Lightning is a common cause of pcboard
failure. The spike or surge of volts can destroy the
board. Also the relays on the board can fail or even
connections. It's most common to replace the board than

How Do I
tell which board I have?
Basically, you ID the board by the label on the upper

before you proceed.
PCboards have jumpers. They are the manual way to tell
