Complete each test within three to five seconds. If time limit is exceeded, possible damage to the starter solenoid may result.
1. Pull-in test at point (A).
a. Connect the magnetic switch to the battery as shown in Figs. 18 & 19.
b. Connect the battery ground cable to the ``M'' terminal and the magnetic switch body (housing): the positive side to the ``C'' terminal.
c. If the pinion has been ejected, the pull-in coil is good.
2. Hold-in test at point (B).
a. Disconnect the ``M'' terminal lead.
b. The pinion should remain in the ejected position.
3. Plunger return at point (C).
a. When the switch body is disconnected, the pinion should return quickly.
3. If the pinion does not operate as specified, repair or replace the starter motor as necessary.
