2.Locate the red, positive (+) battery cable from starter solenoid. Connect it to the positive (+) battery terminal (see Figures 14 and 15).

3.Locate the black, negative (–) battery cable attached to engine block. Connect it to the negative (–) battery terminal (see Figures 14 and 15).

GENERATOR

GROUNDING

WARNING: You must prop- erly earth-ground generator be- fore starting. This will help guard against deadly electric shock. Only use grounded plugs with generator. Only use grounded ex- tension cords. Only use three- wire or double-insulated power tools.

Grounding generator helps prevent electric shock from a ground fault condition. Locate ground lug on end of generator housing (see Figure 16). Attach a #10 stranded-copper ground wire to ground lug. Drive grounding point into ground. Grounding point can be a stake, grounding rod, or pipe. Grounding point should be copper or brass. Attach ground wire to grounding point. You must supply the ground wire and grounding point. These do not come with generator. Follow the National Electrical Code and all state and local codes. Consult your power com- pany or a licensed electrician.

WARNING: For a grounding point, do not use metal pipe be- ing used to carry combustible materials or gases.
