I have a 2018 Scamp 13 with bath. I lost my electric brakes, and I am trying to find the general area where Scamp connected the ground (white) wire to the frame. I have concluded that the Brake Controller (Prodigy P2) is working properly and there is power at the T.V. 7 pin connector for the brakes. Checking the brakes on the Scamp I found that Scamp used a splice tap connector on the left side to power the brakes and this connection was not making contact within the tap. I removed the connector and soldered the connection directly at that same point. I also replaced the ground lug for the brakes on this side. On the right side the wire to the ground lug had broken off so I replaced the ground lug on this side as well. I have been able to verify that from the (white) ground wire on the 7-pin cable on the Scamp I can get continuity to the battery negative wire and also to the ground connection on the marker lights. But I cannot get any connection from the 7-Pin ground wire connector to the frame. And since the frame is not grounded the brake solenoids are not functional. I had hoped that finding those two problems would solve the issue. So where is the general area that Scamp uses to attach the ground system to the frame.
