The bonding jumper or ground, is most of the time on the righthand lower engine mount bolt. One end of the ground goes under the head of the mount bolt and is in contact with the backside of the steel engine mount. the other end is then put on the stud on the bottom of the engine case by the mount bolt. This ground is mostly needed to complete the circuit when the starter is engaged. If it is not there the circuit has to find a lighter sorce for ground witch is not good. Hope this helps. Mark
