36.) When testing a starter battery voltage drops from 12.6 to 9.8 volts during cranking. Which of these should the technician do next? OA. Measure the starter current draw. OB. Repair the starter ground circuit. OC. Replace the battery and retest. OD. Check the charging system.

## Step 1<br />The problem presents a situation where the voltage of a starter battery drops from 12.6 volts to 9.8 volts during cranking. This indicates that the battery is not holding its charge properly, which could be due to several reasons.<br /><br />## Step 2<br />The options provided suggest different courses of action that a technician could take. These include measuring the starter current draw, repairing the starter ground circuit, replacing the battery and retesting, and checking the charging system.<br /><br />## Step 3<br />Given the symptoms described, the most logical next step would be to replace the battery and retest. This is because the battery is the component that is directly responsible for providing the necessary voltage during cranking. If the battery is not holding its charge properly, it would not be able to provide the necessary voltage, leading to the symptoms described.<br /><br />## Step 4<br />The other options, such as measuring the starter current draw, repairing the starter ground circuit, and checking the charging system, could also be potential causes of the problem. However, these are not the most direct causes of the symptoms described. Therefore, the most logical next step would be to replace the battery and retest.
