What is the electrical problem with the 737 Max 8?

The FAA said on April 29 that it is investigating how the electrical problem occurred.

It was found that Boeing had more accidents than expected, while Airbus had fewer (p = 0.015). In terms of fatalities, Boeing had more than expected, with Airbus fewer (p < 0.001). Looking at accidents alone, only the number of fatalities was statistically significantly different.
