Complaint of ineffective low beams. This 4x4 International 7400 workstar has bumper mounted headlamps. Investigation concluded that "ground" and "high beam" wires were swapped, resulting in low beam circuit being completed through both filaments of the headlamp. Output power was greatly diminished and lighting pattern was diffuse. The problem appears to have been fixed by interchanging the "ground" and "high beam" feeds in the headlamp plugs.
