troubleshooting flowcharts for a variety of symptoms. Each flowchart leads you through a series of steps
that will ultimately result in a solution. The solutions begin with the most simple and progress to the most
complex.

Check Internal Voltages and Signals
In addition to the troubleshooting flowcharts, you can also check internal voltages and signals to diagnose
a defective part.
This section includes diagrams of internal voltages and signals that should be present at locations on the
controller ECA, ballast/power supply ECA, and the I/O ECA. You can use this section to verify a problem
that you diagnose from the troubleshooting flowcharts, or you can perform voltage checks as a starting
point for diagnosis.
What do you want to check?
