( ) Which of these could cause a starter motor to make a grinding noise during cranking? CA Comediad solenold contects Cill wom starter brushes CO. A weak battery CO. Wom flywheel teeth

## Step 1<br />The problem is asking us to identify the potential causes of a grinding noise during the cranking of a starter motor. The options provided are: A) Comediad solenold contects, B) Worn starter brushes, C) A weak battery, and D) Worn flywheel teeth.<br /><br />## Step 2<br />We need to understand the role of each component in the starter motor system. The starter motor is responsible for cranking the engine to start it. The solenoid contacts, starter brushes, battery, and flywheel teeth all play crucial roles in this process.<br /><br />## Step 3<br />The solenoid contacts are responsible for transmitting the electrical current from the battery to the starter motor. If these contacts are worn out, they can cause a grinding noise.<br /><br />## Step 4<br />The starter brushes are responsible for transmitting the electrical current from the battery to the starter motor. If these brushes are worn out, they can also cause a grinding noise.<br /><br />## Step 5<br />The battery provides the electrical power to the starter motor. If the battery is weak, it may not provide enough power to the starter motor, which can cause a grinding noise.<br /><br />## Step 6<br />The flywheel teeth are responsible for transmitting the power from the engine to the starter motor. If these teeth are worn out, they can also cause a grinding noise.
