Sounds like someone has jumped fuses in the fuse box. Or you have lost a ground.

Best Answer

I checked the ground already and checked all fuses...

No In cab lights at all? How are you testing the fuses? I would look at the alternators connections as well. Maybe missing one.

Weak connections loose grounds no contact on grounds that appear good. Rule of thumb lights go stupid its a ground

With a volt tester... I traced all wires and all at solid

Use a test light. Check on both points it lights up. Plane ole test light will tell you more. volt meters lie. If there is no damage and nobody has used incab wiring for a power source to something else really all it can be
