attached to the big red wire which goes to the solenoid, All batteries
are to be fully charged before installing. Refer to "Quick Start" battery
guide that came with the operator's manual.

through and exposed the bare wire. Replace the wire or repair with
electrician's tape ifthe wire strands have not been damaged.
