- A control circuit voltage drop test shows a 1.1 volt drop at the starter S terminal. Which of the following could be the cause? High resistance in the solenoid switch circuit High resistance in the clutch safety switch Loose battery cable connection Short in the starter armature windingsarrow_forwardTrue or False? A zero reading on an ohmmeter means the circuit or component is open.arrow_forwardTechnician A says that a 12-volt light bulb that draws 12 amps has a power output of 1 watt. Technician B says that a motor that has 1 ohm of resistance has a power rating of 144 watts if it is connected to a 12-volt battery. Who is correct? Expert Answerarrow_forward
- What happens when the low-voltage current flow in the coil primary winding is interrupted by the switching device? The primary winding delivers a high-voltage spark to the plugs. The magnetic field in the coil primary builds. The secondary voltage drops to zero volts. High voltage is induced in the secondary windinarrow_forwardhile discussing NTC thermistors; Technician A says that some systems use this type of thermistor as a protection device. Technician B says that when there is high current in a circuit, the resistance of the thermistor increases and causes a decrease in current flow. Who is correct?arrow_forwardWhile discussing electric motors: Technician A says that when there is high CEMF, there will be high current flow. Technician B says that if the reluctance of an electromagnet increases, its field strength increases. Who is correct? Technician A Technician B Both A and B Neither A nor Barrow_forward
- Technician A says that a starter no-load test is conducted with the starter in a bench vise. Technician B says that the no-load test is used to determine starter motor circuit voltage drop. Who is correct? Technician A Technician B Both A and B Neither A nor Barrow_forwardTrue or False? A faulty voltage regulator can only cause a no-charge condition.arrow_forwardWhich of the following uses a permanent magnet and two electromagnets? Air-core gauge Balancing coil gauge Quartz analog gauge D' Arsonval gaugearrow_forward
- True or False? Coil secondary resistance is typically very low, less than 1 ohm.arrow_forwardA starter cranks, but cranks slowly. The shop performs a voltage drop on the ground and power side of the starter circuit and they both test good. Technician A says the battery may be bad. Technician B says the starter may be bad. Who is correct?arrow_forwardWhich of the following tests would not be performed to check for high resistance in the battery' cables? Cranking voltage test Insulated circuit resistance test Starter relay by-pass test Ground circuit resistance testarrow_forward
