1. Safety First: Before beginning any examination, it is essential to prioritize safety. Ensure that the equipment is turned off and disconnected from any power source. Wearing protective gear, such as gloves and goggles, is advisable to safeguard against any potential hazards.

2. Visual Inspection: Start with a thorough visual check of the ignition assembly. Look for signs of wear, corrosion, or damage in the connections and wires. Pay special attention to the battery terminals and ensure they are clean and secure. Any visible issues should be noted for further investigation.

3. Check Battery Voltage: Using a multimeter, measure the voltage of the battery. A fully charged battery should read around 12.6 volts. If the reading is significantly lower, it may indicate a need for charging or replacement. Document the results for reference.

4. Examine Connections: Proceed to inspect all connections related to the ignition mechanism. Loose or corroded terminals can impede functionality. Tighten any loose connections and clean corroded ones with a wire brush or appropriate cleaning solution.
