Starting battery. Kohler Co. recommends a separate
12-volt battery for the generator set. With a separate
battery, cables can be kept short, eliminating the
problem of voltage drop through long cables.

cable connections. Connect a ground strap between
the ground lug on the generator set and vehicle frame
