TABLE F.1 – TEST POINTS

MAIN TRANSFORMER TEST (continued)

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.
