When removing a battery from a Diesel engine, which terminal should be removed first?

When removing a battery from a Diesel engine, it is important to always disconnect the negative terminal first. This practice is based on safety and minimizing the risk of electrical shorts.

By removing the negative terminal first, you ensure that the circuit is broken, which reduces the chance of accidental short-circuiting. If you were to remove the positive terminal first and your tool were to touch any metal part of the engine while the positive terminal is still connected, it could cause a short circuit potentially leading to sparks or even an explosion. Removing the negative terminal creates a safer environment, especially when working around live electrical systems.

Understanding these safety procedures is crucial for anyone working with batteries and electrical components, as it helps prevent accidents and injuries during maintenance or servicing of Diesel engines.
