The answer to 'electrical meter not working' is that there are several common causes, including a faulty meter, wiring issues, or a problem with the power supply. Symptoms may include a meter that doesn't display any readings, shows erratic or incorrect readings, or completely stops working.
Some potential solutions include checking the circuit breakers, inspecting the meter and wiring for any visible damage, and testing the power supply. However, if you're not comfortable working with electrical systems, it's best to call a licensed electrician to diagnose and repair the issue.
