Question
6. What type of measurable output is present at the "BAT" terminal of an AC generator? AC Current Pulse Width Modulation (PWM) DC Current None of the above 7. Technician A says that a poor connection at the generator output wire can cause charging systems problems. Technician B says that many charging system circuits contain a circuit protection device. Who is correct? A only B only Both A and B Neither A ar B 8. Technician A says when testing the voltage output, if the charging voltage is too high, the cause could be an open field wire from the regulator. Technician B says a loose or glazed drive belt could be the cause of too high charging voltage. Who is correct? A only B only Both A and B Neither A or B

1. A starter motor cranking speed is noticeably slow. Technician A says that testing the voltage drop of the positive battery cable while cranking the engine will reveal potential problems in the battery. Technician B says that testing the voltage drop on the negative battery cable must be done with the ignition switch in the off position. Who is correct? A only B only Both A and B Neither A ar B 2. A 0.7v (700mv) voltage drop is measured between the negative battery cable clamp and the starter case with the engine cranking. Technician A says this voltage drop reading is normal for a negative battery cable. Technician B says that voltage drop greater than 0.2v (200mv) on the ground circuit is considered excessive. Who is correct? A only B only Both A and B Neither A ar B 3. A good battery should maintain a voltage of or greater when cranking over an engine. 9.6 volts 6.0 volts 12.0 volts 14.4 volts 4. During a starter current draw test, the measured current is greater than specified, and the cranking speed and battery voltages are less than specified. The cause of this problem may be: High resistance in the battery positive cable High resistance in the field windings A burned solenoid disc and terminals Worn bushing in the starter motor 5. Excessive resistance is measured on the ground circuit of the charging system. Technician A says the negative battery cable may be the cause. Technician B says that loose or corroded generator mounting hardware may be the cause. A only B only Both A and B Neither A ar B
