there are only a few stages.
b.
the many stages complicate the wiring.
c.

b.
d.
3. In the wiring diagram in figure 4-1, the identification numbers for the
relay and the interlock switch, respectively, are

E4001 and S4003.
b.
K4001 and B4002.
d.

prevent damage to the ohmmeter.
b.
conserve power not needed for the test.
c.
insure against the transmission of test signals.
d.
obtain an accurate measurement of the charge on the capacitors.
5. Assume that you suspect interlock switch S4003 in figure 4-1 to be
