When should bench testing of a starter be performed?

Bench testing of a starter should be performed after reassembling an old starter and before installing a new starter for several reasons.

When reassembling an old starter, bench testing is essential to confirm that all components are functioning correctly and that the starter is reliable before installation. This prevents potential issues after installation, such as the starter failing to engage or function properly, which can lead to unnecessary labor and vehicle downtime.

Before installing a new starter, bench testing serves as a quality control measure to ensure that the new unit is operational and meets the specifications required for the vehicle. This step helps identify any defects or issues with the new starter prior to installation, reducing the risk of having to remove and replace a faulty starter soon after installation.

Both scenarios emphasize the importance of testing starters in a controlled environment to ensure they perform as expected, enhancing overall reliability and efficiency in the vehicle's starting system.
