Installed in the Power Relay Assembly (PRA), the Pre-charge
Relay connects high voltage circuit when pre-charging the inverter
capacitor.
When the IG is ON, the current coming through the pre-charge
relay and the resistor charges the capacitor in the inverter and when
the capacitor is fully charged, the pre-charge relay turns OFF.
