(4)
Disconnect the ohmmeter.
q.
AC/DC Systems Equalizer Coil Circuit (fig 2-6).
(1)
Set all test stand controls to the preliminary settings listed in table 2-2.
(2)
Connect an ohmmeter between the GENERATOR G+ binding post and the AC/DC SYSTEMS D binding
post.
(3)
Check to see that the ohmmeter indicates 40 to 50 ohms when AC/DC SYSTEMS EQUALIZER COIL
TEST switch (S35) is set to the ON position, and an open circuit when switch (S35) is set to the OFF position.
r.
AC/DC Systems Ignition Circuit (fig 2-6).
(1)
Check to see that circuit breaker (CB1) is set to the OFF position.
(2)
Connect an ohmmeter between the REGULATOR B+ binding post and the AC/DC SYSTEMS IGN SW
binding post.
(3)
Check to see that the ohmmeter indicates continuity when AC/DC SYSTEMS IGN SW (S33) is set to the
ON position, and an open circuit when the switch is set to the OFF position.
(4)
Disconnect the ohmmeter.
s.
Auxiliary Start Circuit.
(1)
Check to see that circuit breaker switch (CB1) is set to the OFF position.
(2)
Connect an ohmmeter between pins A and F of BAT connector (J6, fig 2-4).
(3)
Check to see that the ohmmeter indicates zero ohm when AUX START switch (S39, fig 2-5) is held in the
ON position, and an open circuit when switch (S39) is released.
(4)
Disconnect the ohmmeter.
t.
Field Shorting Circuit.
(1)
Check to see that circuit breaker switch (CB1) is set to the OFF position.
(2)
Connect an ohmmeter between pins D and A of GEN connector (J3, fig 2-4).
(3)
Check to see that the ohmmeter indicates zero ohm when FIELD SHORTING switch (S38, fig 2-5) is held
in the ON position, and an open circuit when switch (S38) is released.
