So I had the SV gauges' speedo working and I moved the wires to get the backlight working and now my speedo is acting all crazy. It reads zero while riding but would display a small number when I came up to a stop. Eventually I realized that it only works while the bike is at IDLE!:dowhat I thought the sensor might have been going out, but it reads and accurate speed while coasting so I dunno. The other thought was a loose wire on the gauge, but that still doesn't explain it.
