CHAPTER 3: Troubleshooting
3.3.1 TROUBLESHOOTING – CONSOLE DOES NOT LIGHT UP
Symptom:
No power to the console.
Solution:
1. Check the connection of the console cable at the console. Unplug the console cable from console, and
use a multi-meter to check the voltage through the console cable. Normally it should be 12VDC
between pin1 & pin8. If no voltage is present, the console cable or LCB is defective. Test voltage at
LCB, if voltage is present replace console. If not, replace LCB.
2. If the voltage through the console cable is 12VDC, the console is defective. Replace it.
