2003 Sportster 150 Gauges not working


New Member
Hey, I have an issue with my 2003 Speedster 150 gauges. The lights on all 4 gauges are working, but the tachometer, speedometer, and fuel gauge are not working. The only working gauge is the warning lights, which seem to be running on separate wiring. I put a multimeter to the positive on the tachometer and the negative and got no voltage. When I put the leads on the negative and the light positive I got 12V. Does anyone know what the issue could be and how to fix it?
