set as follows: (1) Move the generator set master switch to the
OFF position. (2) Disconnect the power to the battery charger.
(3) Remove the battery cables, negative (--) lead first.
Reconnect the negative (--) lead last when reconnecting the
battery. Follow these precautions to prevent starting of the
generator set by an automatic transfer switch, remote
start/stop switch, or engine start command from a remote
computer.

To further check generator set components, disconnect
the battery and remove wiring harness plugs from the
controller circuit board. Refer to the wiring diagrams in
the wiring diagram manual and use an ohmmeter to
check for continuity and good ground connections. A
zero reading on the ohmmeter indicates continuity. No
ohmmeter reading indicates very high resistance or an
open circuit.
