6.0L injector solenoids burning up
 

This is a good one! Working on an 10/04 F450 6.0L. All 8 injector solenoids were faulty. Replaced the main engine wiring harness, positive battery cable, all 8 injectors. Came in next morning and found another injector solenoid has been burnt up by just sitting overnight. Any idea what could be causing this??:argh:
