A short to ground in a circuit will most likely cause:
Answer: A blown fuse
A short to ground creates a low-resistance path that draws high current and blows the fuse.
Lifter tick that disappears as the engine warms up often indicates:
Answer: Collapsed or dirty hydraulic lifters/low oil
Hydraulic lifters can tick when oil is cold or contaminated and quiet as oil flows.
When charging system output is high (over 15V), the most likely cause is a:
Answer: Faulty voltage regulator
An overcharging condition typically results from a failed voltage regulator.
Two resistors of equal value wired in parallel produce a total resistance that is:
Answer: Half of one resistor's value
Equal resistors in parallel yield half the resistance of a single one.
A constant velocity (CV) boot that is torn will most likely lead to:
Answer: Joint failure from lost grease and contamination
A torn boot lets grease escape and dirt enter, destroying the CV joint.
Engine knock or pinging under acceleration can be caused by:
Answer: Low-octane fuel or excessive carbon/timing advance
Detonation (knock) results from improper octane, carbon buildup, or over-advanced timing.
To check for excessive play in a ball joint, the wheel should be:
Answer: Unloaded and rocked/levered for movement
Ball joints are checked unloaded by prying or rocking the wheel to detect play.
