While testing a starting circuit on a 5.7L V8 engine, the technician finds that the engine cranks
slowly. The
starter current draw is 90 amps, and the battery voltage while cranking is 11 volts. What should
the technician do next?
A. Check for voltage drop of the starter motor circuit.
B. Test the battery capacity.
C. Replace the starter motor, as a short Is indicated.
D. Determine the condition of the engine.

B. grounded
C. complete
D. open
.d
A vehicle's tum signals flash too slowly. Technician A claims that the condition could be caused
by a faulty flasher. Technician B says that a bulb may be the wrong type.
