TROUBLESHOOTING BASICS
When your system does not function properly (or as you expect it to operate), the first thing that you must do is identify and isolate the prob- lem. When you have accomplished this, you can effectively begin to resolve the problem.
The first step is to isolate each system component and ensure that each component functions properly when it is run independently. You may have to dismantle your system and put it back together piece by piece to detect the problem. If you have additional units available, you may want to exchange them with existing components in your system to help iden- tify the source of the problem.
Determine if the problem is mechanical, electrical, or
You may be experiencing more than one problem. You must isolate and solve one problem at a time. Log (document) all testing and problem isolation procedures. You may need to review and consult these notes later. This will also prevent you from duplicating your testing efforts.
Once you have isolated a problem, take the necessary steps to resolve it.
