SYMPTOMS

GO TO

Ø

Runs slow in both directions plus high armature and field current in both

directions. NOTE: Armature and field current should be equal.

MOTOR

Ø

Runs slow in both directions plus high armature current in both directions.
NOTE: Field current will be very low.

SOLENOIDS

Ø

Ø

Runs normal in one direction only plus runs slow or lacks power in the opposite

direction with high armature current in the opposite direction or;

Accelerates slowly and exceeds normal speed in the opposite direction with high

armature current only. NOTE: Field current will be very low in the opposite
direction.

SOLENOIDS

Ø

Accelerates slowly and exceeds normal speed in both directions plus high

armature current. NOTE: Field current will be very low.

SOLENOIDS

Ø

Full speed only.

PMC CONTROL

Ø

Does not run in either direction plus there is noise from motor (hum or whine)
with high field current and low armature current.

PLUGGING DIODE

Ø

Excessive spark when connecting battery

ISO

Ø

Does not run or runs very slow with low motor current and high battery current.

FREEWHEEL DIODE

Ø

Jumps into high speed when direction is selected after depressing the accelerator
pedal.
