#BDR Ballast resistors generally
This post/entry is summarised here:
If a ballast resistor is installed in the circuit to the battery instead of the ignition circuit, it is serving a different purpose. To clarify the roles and placements of different types of resistors in automotive electrical systems read on:
### Ballast Resistor in Ignition Circuit:
1. **Purpose**: Manage voltage to the ignition coil.
2. **Placement**: Between the ignition switch and the ignition coil
