Electrical Troubleshooting
Before any maintenance work is carried out, electrical supply must be locked in the OFF position
or the mains lead removed.
Faults on electrical & electronic modules are rare but loose plugs and terminals are responsible for most
electrically based failures. A logical approach to detecting the fault begins with a complete appraisal of the
faults and symptoms.
Much time can be wasted looking in the wrong areas for a problem that, when found, was obvious.
