shorted out
Mechanics' term for lazy diagnosis; workplace humor.
What an ignorant person or dealership tech says the problem is when he or she does not have the mental capacity to properly diagnose an electrical problem in a vehicle. This conclusion is typically drawn after a tech plugs in a scan tool that does not tell him what the problem is and has no clue how to troubleshoot further.
