Final answer:
The remaining service life of starter-generator brushes can be determined by monitoring their wear and measuring the required electrical performance. One way to assess the remaining service life is by measuring the brush length using a caliper. Another method is to monitor the electrical performance of the starter-generator.
Step-by-step explanation:
The remaining service life of starter-generator brushes can be determined by monitoring their wear and measuring the required electrical performance. When the brushes wear down to a certain length, they need to be replaced to ensure proper functioning of the starter-generator. This can be determined by regularly inspecting the brushes and monitoring their performance.
One way to assess the remaining service life is by measuring the brush length using a caliper. As the brushes wear down, their length decreases. Once the brushes reach a minimum length specified by the manufacturer, they need to be replaced.
Another method is to monitor the electrical performance of the starter-generator. If the brushes are worn, they may not make proper electrical contact, causing a decrease in output power. By testing the output power periodically, any significant decrease can indicate the need to replace the brushes.
