Testing Power Supply Instruction

Step 1: Visual inspect Power Supply for damages.

1. Check all wires. Make sure no wires are exposed due to damage.

4. Make sure each connector is putting out the correct voltage. If not, the power supply is now working properly.

5. Turn off the power supply and continue the process with the other connectors.

Step 4: All connector must be working properly in order for the unit to be F3 - key function working. If not, unit must be scrap for recycling.
