	Remove/install
1	Perform disable for the high-voltage on-board electrical system	Model 242 with engine 780
			AR54.10-P-1150NKE
2	Switch off ignition and keep transmitter key at a location beyond transmitter range (at least 2 m)	Model 117, 156, 176, 246 Model 242 with engine 270 All electrical consumers must be switched off. They may otherwise be damaged when the ground line (5) is disconnected/connected.
3	Open engine hood and secure against falling down
4	Unclip retaining clip (2.1) for engine wiring harness (2) from on-board electrical system battery cover (1)	Model 117, 156, 176, 246 with engine 607, 651
5	Unclip engine hood cable (3) from on-board electrical system battery cover (1)	Model 117, 156, 176, 246 Model 242 with engine 270
6	Unlock on-board electrical system battery cover (1) in direction of arrow and remove	Model 117, 156, 176, 246 Model 242 with engine 270
7	Slacken nut (4)	Nut, battery cable to negative terminal/positive terminal of on-board electrical system battery	*BA54.10-P-1007-01I
8	Detach ground line (5) from on-board electrical system battery (G1) and expose in battery box area
9	Using a diode test lamp, check the electrical system for voltage between the positive line of the on-board electrical system battery (G1) and the disconnected ground line (5)	Model 117, 156, 176, 246 Model 242 with engine 270 If the diode test lamp lights up, the on-board electrical system is still active because of a defect in the electrical system.
10	Disconnect ground cable from additional battery	Only when the diode test lamp lights up.
