12.If ALL the voltages tested are incorrect or miss- ing, test for correct nameplate input voltage between the H1 lead at the ON/OFF POWER SWITCH to H2 or H3 at the reconnect panel. Voltage tested will vary depending on input voltage connection. See Wiring Diagram for test point locations.

A.If the input voltage test is incorrect, check for loose or broken leads between the reconnect panel and the ON/OFF POWER SWITCH.

B.Test the ON/OFF POWER SWITCH for proper operation.

13.If the correct nameplate voltage is being applied to the main transformer and one or more of the secondary voltages are missing or are incorrect, the main transformer may be faulty. Replace.

14.When test is complete, replace tool tray, case sides and top.
