Big Bear won’t start

All, could use some help trouble shooting. I have a 350 Big Bear and I won’t start, meaning, when I push the start button it acts as if it is a dead battery. I have replaced the battery with the same result. I am confused as the headlights work, but I have lost all of the lights on the dash (reverse and neutral lights). Before this happened I thought the solenoid was going bad because it chattered some. Should I start with the solenoid, then starter, then maybe the neutral safety switch at the shifter?

Any assistance is greatly appreciated. Thanks
