PSU Voltage Test
For this process you will require a Multimeter
Plug the ClockRite Power Supply into a socket that you know works correctly
Connect your Multimeter cables
Turn the setting to DCV 20 (as shown below)
Connect the RED testing end INSIDE the connector from the transformer
Touch the BLACK testing end to the OUTSIDE of the connector.
The multimeter will now show the voltage coming out.
If you see a ZERO reading this means that the transformer has FAILED and must be replaced.
