Just bought an 03 sunsetter 23 xti, knowing speedometer and lcd were not working hoping for a relatively easy fix. Not easy so far. Wondering if anyone has had the same issue I’m having or some advice on troubleshooting. I’ve read about a couple similar problems on here that have helped a little. I checked the 2 inline fuses under dash. Unplugged cannon plug on engine ( looked great) spread puns apart slightly. I took gauge bezel off and found speedo plug disconnected. When I connected it and powered up the gauges it did it’s normal buzzing just like all others and then lcd displays “no data”. About 30 seconds later all other gauges power down on their own, wtf. Disconnect speedo again and all others function normally. Disconnected each gauge,lake temp, air temp, depth sounder etc...(everything connected to MDU) one at a time and all at once with speedometer connected (I’ve seen others say 1 bad gauge can take out another)and same “no data”is displayed on lcd.
I’ve tried a couple other things but I’ll try to keep this first post shortish.
thanks in advance
