They normally have the ground connection through the body or housing of the generator itself ...to the motor ..then onto the chasiss ..onto the body etc... It's worthwhile installing a heavy braid ground strap from the motor to the cab at somewhere convenient. A lot of poor starting problems can be traced to poor grounds . I think some vehicles have a dedicated ground wire from the gene as well ..depends on how it is set up..look at your wiring diagram.
