Troubleshooting
Checking the PWR Board
Voltages
To measure the output voltages of the PWR board, check the voltages at J2000
on the AWG12G board with the multimeter and compare each reading to the
values listed in the following table. If the voltages are within the allowance,
your PWR board is functional.
