8 Troubleshooting
Improper or incorrect wiring is the cause of most problems. The first step in troubleshooting is therefore
always to check all wiring for loose connections or possible shorts/opens. The next step is to check for the
most common failures.
Solve a problem by following the corresponding corrective action. If the problem still remains, contact the
assembler of the system.
