I recently added an XM satellite receiver to a '82 300SD. All the wiring, except for the ground wire, connected to the wiring on the Becker radio head. All works fine...UNTIL I turn on the headlights. The radio/XM still works but the dash lights don't. On further checking, I realize every time I turn on the headlights, the fuse for the dash lights blows. Any leads or suggestions? Could a poor ground be the problem?
