Do not start the vehicle while the battery charging cable is connected
and the generator is running. The vehicle or the generator may be
damaged.
An overloaded DC circuit, excessive current drawn by the battery, or a
wiring problem will trip the DC circuit protector (the yellow indicator
inside the clear circuit protector button will pop out). If this happens,
wait a few minutes before pushing in the circuit protector button to
resume operation. If the circuit protector continues to go OFF,
discontinue charging and see your authorized Honda generator dealer.
Disconnecting the battery charging cable:
1. Stop the engine.
2. Disconnect the black lead of the battery charging cable from the
battery negative ( ) terminal.
3. Disconnect the red lead of the battery charging cable from the
battery positive ( ) terminal.
4. Disconnect the battery charging cable from the DC receptacle of the
generator.
5. Connect the vehicle ground battery cable to the battery negative ( )
terminal.
