What should you inspect on a starter and starter solenoid?

When inspecting a starter and starter solenoid, the focus should be on the physical condition and security of the components. Corrosion can indicate poor electrical connections and lead to performance issues, creating reliance on the starter and electrical system's proper function.

Examining the security of mounting bolts is crucial, as loose connections can cause faulty operation or damage to the starter system. Discoloration, often a sign of overheating or electrical failure, should also be monitored. Any signs of corrosion or discoloration could point to potential electrical problems that may affect the reliability and efficiency of the starter.

In contrast, fluid levels and filters are not relevant to starter and solenoid checks, since these components don't operate with fluids like internal combustion engines. Wiring diagrams and fuses are essential for troubleshooting electrical systems but aren’t part of the physical inspection process. Lastly, while checking battery voltage and amperage is important for the overall starting system functionality, it does not pertain specifically to the physical inspection of the starter or solenoid itself. Therefore, focusing on corrosion, bolt security, and discoloration is the most accurate approach when assessing the condition of a starter and its solenoid.
