7.Carefully apply the correct input voltage to the Power Wave 455M.

WARNING

ELECTRIC SHOCK can kill.

High voltage is present at prima- ry of the Auxiliary Transformer.

8. Turn on PW455M.

10.If the correct secondary voltages are pre- sent, the T1 auxiliary transformer is func- tioning properly. If any of the secondary voltages are missing or low, check to make certain the primary is configured correctly for the input voltage applied. See the Wiring Diagram.

11.If the correct input voltage is applied to the primary, and the secondary voltage(s) are not correct, the T1 transformer may be faulty.

12.Replace any cables ties and insulation removed earlier.
