on the wires is not worn or damaged. The
starting circuit should be given a voltage
loss test to make sure there is no loss of
starting motor efficiency due to high resis-
tance connections. In making this check, the
voltage loss from the battery terminal to the
starting motor terminal should not exceed .30
volts maximum for each 100 amperes. The loss
in voltage between the battery ground post
and the starting motor frame should not
exceed .10 volts maximum for each 100
amperes. If the voltage loss is greater than
the above limits, the voltage should be
measured over each part of the circuit to
locate the resistance causing voltage
loss.
If the commutator is dirty or discolored, it
can be cleaned with No. 00 sandpaper. Blow
the sand out of the motor after cleaning.
Should the commutator be rough or worn, the
motor should be removed from the engine for
cleaning and reconditioning.
The brushes should slide freely in their
holders and make full contact on the commu-
tator. Worn brushes should be replaced.
No on-the-car lubrication is required.
