appears.
If the start battery contactor trips due to an over-current condition, the start battery is
isolated from the electrical system and a START BATT CONTACT TRIP advisory
appears.
NOTE:
Engine start is not possible with the start battery isolated.
START BATTERY CONTACTOR AND LIGHTING CONTROLLER
The start battery contactor and lighting controller is a self-contained unit that houses
the following electrical components.
1. Start Battery Contactor
2. Hot Battery Bus
3. Interior Lighting Controller
4. 125 A Fuse for the Air Conditioning System
In addition to housing the start battery contactor and the 125 amp fuse for the air
conditioning, the Start Battery Contactor and Lighting Controller also houses the hot

battery switches off. A lighting controller function internal to this unit allows for control
and regulation of internal lighting along with the internal timer to deactivate those
lights after five minutes.
