Perform this test on the starter motor positive terminal.       Tighten to 8 ft-lb.
To access the terminal, slide the boot away.
  NOTE: The ignition switch must be in the ON
position, the emergency stop switch in the RUN
position, and the shift lever in the NEUTRAL posi-
tion.

 1. Set the meter selector to the DC Voltage position.
 2. Connect the red tester lead to the starter terminal;
    then connect the black tester lead to ground.
 3. With the starter button depressed, the meter must
    show approximately 10.0 DC volts and the starter
    motor should operate.                                                                                        KC201A
