Circuit Board, Changing - Husqvarna P 520D Workshop Manual

Circuit Board, Changing

IMPORTANT!
It is important to check the circuit outside of
the circuit board first, to ensure this is correct,
before replacing the circuit board. This is
partly due to cost, but also so that no external
fault can damage the new circuit board.
