What is the reason for the high circuit of Guangqi Honda Binzhi start relay 2?

Reasons for high circuit of Guangqi Honda Binzhi starter relay 2;

1. First, the relay controls the voltage across the coil. Because the coil is an inductive load, the voltage will rise rapidly when it is suddenly disconnected.

2. The second is the voltage at both ends of the relay contact. If it is an inductive load, it will suddenly disconnect and the voltage will rise rapidly.

3. The use of free-wheeling diode can suppress these two situations.
