STARTER ASSEMBLY TEST/REPLACE (CONT).
a.
Connect multimeter (1) from motor terminal (2) to
ground terminal (3).
b.
Place rpm indicator (4) on armature shaft (5) to
measure armature speed.
c.
Connect ammeter (6) in series between solenoid
terminal "BAT" (7) and positive terminal of fully
charged battery (8).
d.
Close switch (9) and compare the rpm current and
voltage reading with the following readings:
minimum voltage 20 Vdc
minimum amperage 60 amps
maximum amperage 75 amps
minimum rpm 6500
maximum rpm 7700
NOTE
It is not necessary to obtain the exact voltage specified as an accurate interpretation can
be made by recognizing that if the voltage is slightly higher the rpm will be
proportionately higher, with the current remaining essentially unchanged.
Make disconnections only with the switch open.
