FIGURE 59: STARTING MODULE
This module houses supercapacitors that derive
power from the vehicle electrical system and
discharges it when starting the engine.
On engine start-up, the module provides power
in parallel with the standard batteries. If the
standard batteries are depleted, the module will
provide enough power for engine start-up.
A vehicle equipped with a starting module will
have a differing starting switch arrangement on
the dashboard. This system uses an on/off
ignition switch and an engine starting (cranking)
switch.
