It started with showing 180 on display so I changed the limit switches on mast and the k6 relay. Lasted a week and then would not start up no display, changed the k4 and k5 relays and it lasted a week. Started to show the 180 sometimes and I think steer angle on display. I wiggled the plug that the limit switch wires run to the board and would get those displays on screen and then they went away. Used a zip tie on the plug and it lasted a couple days. Should I replace the board and plugs or am I missing something?
