Battery Disconnect Switch
(If Equipped)
SMCS Code: 1411; 1411-B11
The battery disconnect switch and the engine start
switch perform different functions. Turn off the battery
disconnect switch in order to disable the entire
electrical system. The battery remains connected to
the electrical system when you turn off the engine
start switch.
Turn the battery disconnect switch to the OFF
position and remove the key when you service the
electrical system or any other components.
Also turn the battery disconnect switch to the OFF
position and remove the key when the engine will not
be used for an extended period of a month or more.
This will prevent drainage of the battery.
NOTICE
Never move the battery disconnect switch to the OFF
position while the engine is operating. Serious dam-
age to the electrical system could result.
To ensure that no damage to the engine occurs,
verify that the engine is fully operational before
cranking the engine. Do not crank an engine that is
not fully operational.
Perform the following procedure in order to check the
battery disconnect switch for proper operation:
1. With the battery disconnect switch in the ON
position, verify that electrical components are
functioning. Verify that the hour meter is displaying
information. Verify that the engine will crank.
2. Turn the battery disconnect switch to the OFF
position.
