Battery isolator
1. The vehicle is equipped with a battery isolator that sup-
plies battery power to the vehicle. The battery isola-
tor is controlled by the vehicle controller and the timed
disconnect switch located at the rear of the machine
in the battery box.

2. The vehicle controller will turn ON the battery isolator
with the following inputs:
• Timed disconnect switch
• Key switch
• Door switch
3. Under normal operation when the timed disconnect
switch is in ON position (switch closed) and the oper-
ator either opens the door or turns the key switch from
OFF to ACC or ON position, the vehicle controller will
turn ON the battery isolator.
4. The vehicle controller will turn OFF the isolator when
the key switch has been in OFF position for a period of
time (about
5 min ) to allow vehicle functions to com-
plete prior to turning OFF the battery isolator.
5. If the timed disconnect switch is in OFF position
(switch open), the vehicle will not turn ON the battery
isolator.
6. If the timed disconnect switch is in ON position (with
key in OFF position), but for 5 min none of the actions
before described are carried out or the machine is not
used, the power supply is excluded through the UCM
and the relays.
To restore the power supply, switch to OFF position
first and then switch back to ON position or turn the
key to ON position.
7. The operator can hear an audible “click” when the bat-
tery isolator opens and closes.
