Battery Description
Starting batteries are usually the lead-acid type. Use a 12-volt group 51 battery with a minimum rating of 500 cold cranking amps
at 0°F. The generator set uses a negative ground with a 12-volt engine electrical system. See Figure 26 for battery connections.
Make sure that the battery is correctly connected and the terminals are tight.
Note:
The generator set will not start and circuit board damage may occur if the battery is connected in reverse.
