I have just purchased a 2003 Hurricane 226R with a 4 stroke 115HP Yamaha outboard. None of the instruments work. I have some wiring diagrams from the previous owner but nothing that shows how the gauges are wired. I have removed the instrument panel and I do not have 12V to the gauges. Tracing the red and black power wires back it looks like they are together in a single harness that comes out at the motor. These red and black wires hit a connector in the engine and following that looks like they go to the tilt trim switch. I am pretty sure I lost the wires in there somewhere as I don't think this is correct. I would expect the instruments panel would get power from the ignition switch but I haven't found any connection.
Does anybody have instrument and motor wiring diagrams for this boat or something close? I was really expecting to find a loose or corroded connection between the gauges and ignition but I cant find any wires from the gauges to the ignition.
