It is possible that there was a problem with the truck before you bought it. If the check engine light is still on, have the codes read. There may be a problem with the electrical circuit.
Aadams, usually when guages go whacko like that, look to your ignition switch to be the culprit on our platform.
Its the same problem im having so if u find an answer please let me know. Mine comes on only when i turn the headlights on. All my guages drop and all my dummy lights come on.
It is possible that it is a bad ground. This video on YouTube describes how to fix it. https://www.google.com/url? sa=t&source=web&rct=j&url=%23&ved=2ahUKEwif4ue Z6ZbhAhUFO60KHRdBB98QwqsBMAF6BAgJEAU&us g=AOvVaw0VTJzWxrN8ZFOD4xbU2nov
