Question

5 multiple choice 1 point ecm output to the ignition coil is good, but there is no spark. the problem is most likely a defective ___. the defect cannot be determined from this information. ecm input sensor ignition coil 6 multiple choice 1 point two twelve volt batteries connected in parallel will give you - 6 volts 12 volts 24 volts none of the above

Explanation:

Question 5

The ECM (Engine Control Module) output to the ignition coil is good, meaning the ECM is sending the right signal. An input sensor provides data to the ECM, but a bad input sensor wouldn't directly stop the ignition coil from producing a spark if the ECM output is good. Since the ECM output to the ignition coil is good but there's no spark, the ignition coil itself (which is responsible for creating the spark) is the most likely defective component. The option "The defect cannot be determined..." is incorrect as we can deduce, and ECM is ruled out by good output. Input sensor issues don't directly relate here.

Step1: Recall parallel battery voltage rule

When batteries are connected in parallel, the voltage remains the same as the voltage of a single battery. The formula for voltage in parallel for identical batteries is $V_{parallel}=V_{single}$, where $V_{single}$ is the voltage of one battery.

Step2: Apply the rule to the problem

Each battery is 12 volts. So two 12 - volt batteries in parallel will have a voltage of 12 volts.

Answer:

D. Ignition coil
