If a customer experiences shocks from their vehicle, what is the first test to perform?

A ground check of the vehicle
A voltage check of the battery
A polarity check of the shore cord
A continuity test of the wiring

The correct answer is: A polarity check of the shore cord

When a customer experiences shocks from their vehicle, conducting a polarity check of the shore cord is crucial as it determines whether the electrical connections are correctly aligned. Shore cords connect an RV to an external power source, and if the polarity is reversed, it can cause electrical shocks or other safety hazards. Ensuring that the ground and live wires are correctly wired is an essential first step to prevent electrical malfunctions and protect both the vehicle and its occupants. Other tests may contribute to troubleshooting the problem, such as checking the ground, battery voltage, or continuity in the wiring. However, verifying the polarity of the shore cord specifically targets a common issue that leads to shock risks, making it a vital first step in ensuring safety and functionality.
