k.
Testing After Repair Or Overhaul.
(1)
Connect starter motor for no-load test using
suitable instruments, battery cables and
connecting wiring as illustrated. Note the
following:
(a)
Secure starter motor in suitable test
stand to check operation.
(b)
Use a momentary contact, pushbutton
switch in test circuit for quick release
if very high current surges are
encountered.
(c)
Make all connections or
disconnections with switch open and
carbon pile load turned off.
(d)
If sparking or current flow in the
battery circuit is noted when making
connections, the starter motor
solenoid switch contacts may be
frozen shut (refer to Troubleshooting).
(e)
As the last step in making the test
connection, ground the negative
battery cable securely to a clean metal
ground on starter motor frame
(f)
The carbon pile load is used to adjust
operating voltage for comparison with
specifications. It may not be
necessary in all cases but should be
used to eliminate the need for
interpolation of test data.
