d. BLOWERS AND LAMPS, ETC. TROUBLESHOOTING
Blowers and lamps, etc., troubleshooting is accomplished by deduction of
symptoms.
If no airflow can be felt at top of cabinet or no blower noise can be
heard, you can determine from these symptoms that the blower has malfunctioned. If
a lamp is not lit when it should be, you can determine that the lamp is burned out,
etc.
e. CABLES AND HARNESSES TROUBLESHOOTING
The cables and harnesses troubleshooting is accomplished by elimination and is
described in the Electronics Troubleshooting Flow Chart in this paragraph.
f. GLASS AND MECHANICAL TROUBLESHOOTING
Glass and mechanical troubleshooting is accomplished by functional inference.
For example, if the light source in the OSG is operating, but the light beam is not
received at the outlet port, the functional inference is that one or more of the
fixed mirrors is not reflecting the light beam.
