Solutions |
| 1. Be sure to turn the power off when connecting or disconnecting wires during trouble shooting of the power supply Check the input side of the Power Supply If there is no input power then see above question No. 357. If there is input power then: Disconnect the Power Supply output wires going to Ajunc Board at the Ajunc Board JP3 connector and check the supply side of these wires for the proper voltage with respect to ground If testing the Condor Power Supply only check for +12 volts DC between the black and red wires, pins 1 and 3 on the JP3 connector If testing the Protek Power Supply then check for +5 and +12 volts DC. For +5 volts DC read between the black and orange wires pins 1 and 2. For +12 volts DC read between the black and red wires pins 1 and 3. If the proper voltages are not present then change the Power Supply If voltages are present then disconnect ALL other wires connected to Ajunc Board including the Digital Predg board and Printer if one is present Then reconnect the Power Supply output wires. If the output voltages disappear again, including the +5 volts on units with a Condor Power Supply, then replace the Ajunc Board. (for units With a Condor Power Supply, also replace the 5 volt Power Transistor mounted to the back of the Electronic Box). If the Power Supply output voltages are present, then while monitoring those output voltages reconnect the wires one at a time making certain to turn off the power before connecting each wire. Whichever connection results in a lost output, the wiring should be checked for shorts. If no shorts are found then the device connected to those wires should be inspected and most probably replaced. |
