There is not. The black wire goes directly to the back of the Inverter and then out of the invertor to a ground. The two black wires in the inverter may be tied together on the inside but there is no short wire directly to the frame.

Not sure if these help at all. The first pic is with the meter touching the screws for the red and white wire on the end of the converter. The second pic has the probe on the red wire screw and the bare ground wire hooked to the converter. The third is just the breaker/fuse panel.
