POWER BOOSTING REGULATOR (PBR)

The PBR is a power distribution device for all major

vehicle electrical circuits. It controls stator voltage and

maximizes electrical power or wattage output using its

outputs. The PBR processes the stator's 3-phase AC

output power and controls the output circuits, including a

3-phase ground shunt circuit.

• The 16 volt ECU circuit, powers the injectors, ignition

coils, and system sensors.

• The 14 volt engine circuit, also sometimes referred to

as the 'critical' circuit, powers the fuel pump, electronic

oil pump and EVES Learn Relay. The EVES Learn

Relay powers the EVES Actuator, instrumentation,

headlights and tail light.

• The 14.4 volt chassis circuit, powers the hand

warmers, thumb warmer, and accessory DC power.

The battery charge relay powers the battery charge

• The 3-phase ground shunt circuit carries any unused

3-phase power to ground.
