PROCEDURE

1.Remove main input supply power to the V450- PRO.

2.Remove any output load that may be connect- ed to the V450-PRO.

3.With the analog ohmmeter, measure the resis- tance between the positive and negative output terminals. Refer to Figure F.13.

Important: The positive (+) meter probe must be attached to the positive output terminal and the negative (-) meter probe must be attached to the negative output terminal.

4.If the reading is approx. 50 ohms, the output rectifier modules are not shorted. If the reading is less than 10 ohms, one or more of the rectifi- er modules may be shorted. Reverse meter probe and verify low reading.

5.Remove the case top perform the Input Filter Capacitor Discharge procedure.

6.Using the 5/16” wrench, remove and insulate lead 202A from the negative output terminal. Repeat step 4 to confirm if it is less than 10 ohms short.

7.Reconnect lead 202A to the negative output ter- minal.

8.Replace the shorted modules if necessary.
