PROBLEM

The battery charger supply circuit fuse is too small on 3456 & 3406 common design generator sets and may fail, thus resulting in loss of power to the battery charger. Generator set batteries will not charge and may drain to a level insufficient to start the generator set. Eventually, the generator set controller will cease to operate.
