CHAPTER 4: TROUBLESHOOTING

4.1 Troubleshooting – No Power to the Console – Continued

4. If the MCB does have power, check the connection of the console cable wire at the MCB and UCB.

a. Remove the console cable from the MCB, and use a multi-meter to measure the DC voltage

between the “GND pin” (Pins 4 & 5) and the “+ 15V Pin” (Pins 7 & 8). DC output is normally around

15VDC. If there is no output, replace the MCB.

b. If output is around 15VDC, check the console cable for pinches or kinks. If any damage is found,

replace the console cable. Disconnect the console cable at the UCB and measure the DC voltage

between the “GND pin” (Pins 4 & 5) and the “+ 15V Pin” (Pins 7 & 8). DC output is normally around

15VDC. If there is no output, replace the console cable.
