Set LOAD SELECTION 50 AMPS/25 AMPS switch (S22) to the OFF position. Set LOAD SELECTION 50
AMPS/25 switch (S21) to the ON position. Using an ohmmeter, verify that the resistance between the REGULATOR B+
and REGULATOR B-binding posts is 0.57 ± 0.03 ohm.
(9)
Set LOAD SELECTION 50 AMPS/25 AMPS switch (S21) to the OFF position. Set DC AMMETER LOAD
& STARTER OUTPUT CURRENT BATTERY CHARGE CURRENT RANGE switch (S14) to the LOAD X10 position. Set
LOAD SELECTION 50 AMPS/25 AMPS switch (S20) to the ON position. Using an ohmmeter, verify that the resistance
between the REGULATOR B+ and REGULATOR B-binding posts is 0.57 ± 0.03 ohm.
(10)
Set LOAD RESISTANCE 50 AMPS/25 AMPS switch (S20) to the OFF position. Set LOAD SELECTION
100 AMPS/50 AMPS switch (S19) to the ON position. Using an ohmmeter, verify that the resistance between the
REGULATOR B+ and REGULATOR B-binding posts is 0.285 ±0.01 ohm.
(11)
Set LOAD SELECTION 100 AMPS/50 AMPS switch (S19) to the OFF position. Set LOAD SELECTION
100 AMPS/50 AMPS switch (S18) to the ON position. Using an ohmmeter, verify that the resistance between the
REGULATOR B+ and REGULATOR B-binding posts is 0.285 +0.01 ohm.
(12)
Set LOAD SELECTION 100 AMPS/50 AMPS switch (S18) to the OFF position. Set LOAD SELECTION
100 AMPS/50 AMPS switch (S17) to the ON position. Using an ohmmeter, verify that the resistance between the
REGULATOR B+ and REGULATOR B-binding posts is 0.285 ±0.01 ohm.
(13)
Set circuit breaker switch (CB1) to the OFF position.

Battery Voltage Selector Circuit.
(1)
Set all test stand controls to the preliminary settings listed in table 2-2.
(2)
Disconnect all batteries from the battery compartment (fig 2-9) battery terminals.
(3)
Set circuit breaker switch (CB1) to the ON position.
(4)
Set BATTERY CIRCUIT SELECTOR switch (S6, fig 2-5) to the 24V position. Check to see that 24 VOLT
indicator (DS6) lights.
(5)
Using an ohmmeter, verify that continuity exists between the 24V battery terminal and the STARTER +
INPUT binding post (fig 2-6).
(6)
Set BATTERY CIRCUIT SELECTOR switch (S6) to the 12V position. Check to see that 12 VOLT indicator
(DS5) lights.
(7)
Using an ohmmeter, verify that continuity exists between the 12V battery terminal and the STARTER
INPUT binding post.
(8)
Set BATTERY CIRCUIT SELECTOR switch (S6) to the 6V position. Check to see that 6 VOLT indicator
(DS4) lights.
