ASE A6 Electrical/Electronic Systems
Certification — Practice Questions & Answers
Battery & Starting Systems
Q1: A battery repeatedly goes dead overnight.
Which test is MOST appropriate to find the
cause?
• A. Voltage drop test
• B. Load test
• C. Parasitic draw test
• D. Hydrometer test
,Rationale: A parasitic draw test measures key-
off current draw to identify excessive electrical
loads draining the battery.
Q2: A fully charged 12-volt battery at rest
should measure approximately:
• A. 11.5 volts
• B. 12.0 volts
• C. 12.2 volts
• D. 12.6 volts
Rationale: A healthy, fully charged battery
typically measures about 12.6 volts with no
load.
Q3: A battery labeled "700 CCA" means it can:
, • A. Produce 700 amps of current during
recharging
• B. Be safely discharged to 700 volts
• C. Deliver 700 amps at 0°F for 30 seconds
while maintaining 7.2 volts
• D. Be charged at 700 amps
Rationale: CCA (Cold Cranking Amps) measures
the battery's ability to deliver current at 0°F for
30 seconds while maintaining at least 7.2 volts.
Q4: A starter solenoid clicks but the engine
does not crank. What is the MOST likely
cause?
• A. Weak battery
• B. High resistance in starter circuit
• C. Faulty ignition switch
, • D. Shorted armature
Rationale: Clicking indicates solenoid
engagement, but high resistance prevents
sufficient current from reaching the starter
motor.
Q5: The battery terminal posts and cable ends
show corrosion. Technician A says this can
cause a no-start condition. Technician B says
corrosion increases electrical resistance. Who
is correct?
• A. Technician A only
• B. Technician B only
• C. Both A and B
• D. Neither A nor B
