some Duster gauges not working?

after driving the car today for the first time this year, alternator gauge is out as well. does that mean it is still most likely the IVR? still not sure if the lights on the gauges work or if those are out as well. speedometer works fine though to confirm. radio seems to be out, not sure if that is related or not but just thought i would mention it. I won't be using it so its not a major thing needed to fix.
