9. Basic Fault Finding
9.1. General
This section is intended to help with fault finding down to easily replaceable components (i.e.
to PCB assembly level).
The following are guidelines on how to approach the diagnosis of a fault in the system:
1. Assemble all relevant information on the iGC and any other systems that interface with
the iGC. This might include:
a. Manuals
b. System drawings (particularly electrical diagrams)
2. Have a good set of diagnostic tools
3. Start at the general & work towards the particular
4. Use all the information available. For example:
a. Are any other systems malfunctioning?
b. Are all functions malfunctioning or just one or a few?
c. Are there connections between these faults?
9.2. Fault Symptoms
The following table gives a list of fault symptoms with components to check in order to narrow
down the cause of the likely fault. This should act as a pointer towards which items should
be replaced.
