If you had a short the controller would say "short" or "overload" or some such. You have an open circuit which is a broken wire, cut wire, bad connection etc. Since none work, the issue is probably somewhere between the 7 pin connector and the first split to the wheels. Need a test light to poke at the wire. The ground is also connected through the 7 pin connector but if the lights work you must have a ground working.
