Service Technicians vs. Auto Mechanics

I suppose the biggest differentiation between techs n mechanics is can you repair a component or Do you just replace it. A couple of examples would be , you break off a hardened stud in an aluminum head, now what . Replace the head or drill and extract , another example . You cruise won't shut off your brake lig hts do not work it's 11 o'clock at night you need to be somewhere by morning . do you take the switch up parts and repair it or do you wait for morning to buy a new switch . I work for a heavy equipment dealer ,when doing a repair obviously we have to replace the units for warranty purposes w . but if you have an old guy was old equipment out of warranty not looking for anything else but to get running you make an efficient expedient repair with what you have available . this requires you to think outside the box I know they cars trucks and machinery are all different animals but they all work the same .everything now has can bus multiple computers and on board diagnostics II or OBDII . not to take anything away from technicians it takes a lot of smarts to understand all of these systems work together but I see some of these kids come out of school and call themselves technicians that could . not remove a broken screw or loosen a seized pipe.fitting. but I have seen other kids come out of technician training school and look for knowledge in the shops . it's out there it doesn't cost anything but just to ask . I think I am only met 2 mechanics in my life that would not share information everyone else has always help me to get to where I am now never right of the old guys they are willing to adapt just resistant to change .
