I have a 2003 gtx limited supercharged I just bought. The gauges worked when i bought the ski. Second time i checked the rpm gauge stopped working. About an hour later when I got it home, they stopped working all together. I cleaned all the battery connections, found the 3 amp fuse blown for the beep. Replaced the fuse, and I am getting one long beep upon start up. Could this just be the gauge crapped out as I bought it? I unplugged the cluster and found that I have 12 volts. Is there any way to check the gauges without plugging it in to another ski? Will any other gauges be compatible with these? Any help would be appreciated.Thanks...............Mike
