5.2.14 ELECTRICAL SYSTEM

All trailers are equipped with an electrical system for providing power for lights and electrical controls. All components are designed to minimize the effects of foul weather and adverse operating conditions. However, it is the responsibility of the operator to check and verify that all components are in good condition and functioning as intended.

During the daily or pre-trip inspection, always verify that each light functions as required. It may be helpful to work with another individual to verify the function of the brake or turn signal lights. A properly functioning electrical system is the only way an operator can communicate his intentions to other drivers. Checking the electrical system includes but is not limited to:

1. Replace any bulb that is burned out.

2. Clean all reflective lenses. Replace any that are cracked or broken.

3. Clean all connections and terminals to a light that is flickering.

4. Reroute and secure any wires or cables that are dangling or have snagged on something.

5. Check the integrity of the seal around each light. Replace any seal that is cracked or damaged.

6. Annually (or more often as necessary) check and re-seal all connectors with a nonconductive grease.
