Rob, I think you are missing the point. It has nothing to do how you are attaching the tether. The problem is caused by not enough slack in either the harness in the tender or the one in the engine. The symptom is when you try and move the tether in your hand you feel resistance before you reach the end of the swing. That resistance is trying to pull the harness out of the connector. The fix is to pull the shells off the tender or engine and give some more slack to that harness. Might mean cutting a wire tie.
If you don’t feel comfortable doing this then send it out.
Pete
