HUGE props to Castle for helping me figure this issue out...even when I bought it used. That's customer service!
Excellent news. Glad they were able to help you out. They are able support everything we've ever made. Even products we haven't sold for 10+ years, they are able to do diagnostics over the phone.
In engineering, we spent a while looking at that wire harness trying to make it as safe as possible just in case it was plugged in backwards. That's why some of the wires cross each other before going into the plug.
