8. With the volt/ohmmeter, test THAT THERE

IS CONTINUITY between the leads in the
following groups according to the voltage
for which the machine is wired:

For 200-230 VAC:

A. Test for continuity between leads #9A,

#9B, #9C, #9D, #9K, #9J, and POS con-
nected together at the reconnect switch.

B. Test for continuity between leads #12A,

#12B, #12C, #12D, #12K, #12J, and NEG
connected together at the reconnect
switch.

For 380 - 460 VAC:

A. Test for continuity between leads #9A,

#9B, #9K, and POS connected together at
the reconnect switch.

B. Test for continuity between leads #9C,

#9D, #9J, #12A, #12B, and #12J connect-
ed together at the reconnect switch.

C. Test for continuity between leads #12C,

#12D, #12K and NEG connected together
at the reconnect switch.

9. If there is continuity within the groups of

leads tested, the test is complete. Install
the machine case sides, top, handle and
the lift bail rubber gasket.
