Alright, so I’m new to the forum. I have a little side business of working on bikes and 4 wheelers and what not and I’ve ran into an issue with one of my customers bikes. When I picked it up he had tried to wire in a new ignition by cutting the wires and splicing them and he had extra wires it was the wrong switch it was just a mess. So I took it back to my shop to check it out. When I turned the key the bike lit up but no response from the starter button. It doesn’t turn over or anything. So I put it in dealer mode since it was throwing a code. It said c42 which is improper signal to the ecu. Well I got a new switch. The right one, plugs right in, turn the key lights come on but still no response at the start button and it still says c42. It is important to mention that the wires were just twisted together and that it did turn over once for my customer when he connected the brown and orange wire. So my train of thought is somewhere along the line either when he was wiring it or afterwards when the connections were all right next to each other exposed they crossed and it blew the ecu?? I’m at a loss I just need some direction here, thanks in advance for the help.
