Yamaha Digital Gauge HELP

[musicthornton]

Looking for any suggestions on what my problem might be. I have the 2002 Yamaha digital gauges, multifunction speedo and multifunction tachometer. They power up, but I'm not getting the info. The only thing that works is the RPM reading. Fuel level, speed, Oil, etc are NOT working. They just flash. Everything appears hooked up correctly. Am I missing a fuse somewhere? The fuses in my fuse box all check out ok. This is on a 2003 Ranger 522VX with a Vmax 250. I'm assuming the chances that all the senders went out at once are slim. I'm scratching my head frustrated on this one. Any ideas? Thanks...

If it powers up then fuses are ok. Speed pikup hole in gearcase is probably plugged up and needs to be cleaned, check fuel sender in gas tank, may need new one.
