MOTOR TESTS
The armature and motor housing are not available as
individual parts. The Curtis handheld can show specific
motor faults (See FAULT TESTING on page 91). The
motor can also be tested using a DVOM (See AC Motor
Bench Test on page 122). Additionally, when a test of the
power wiring system indicates that the system is operat-
ing correctly and the vehicle either does not run or runs
poorly, the motor is the only remaining component and
should be replaced.
