Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Generator Battery Disconnect Control Module Cover
The generator battery disconnect control module cover, sometimes referred to as the battery disconnect unit cover (or BDU cover), is a serviceable, hinged panel attached to the rear of the generator battery carrier assembly. This cover shields personnel from intermediate voltage potential when properly secured in a closed position. The service disconnect switch plunger rests against the generator battery disconnect control module cover such that the switch will open with the cover in an open position, and it will close when the cover is in a closed position. The cover is securely fastened to the generator battery carrier assembly by an M6 bolt with a 10 mm hex head.
