12. If ALL the voltages tested are incorrect
or missing, 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 con-
nection. 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.
