Landsteiner, Doing one field, an opining about another is ridiculous. Sure, you can have some insight, but it you really want to know how a process works, you need to do it, not supervise it. This has nothing to do with competition, there is plenty of work to go around, and many techs on this forum push stuff to other techs depending on work load. Again, you stir a pot when your not even competent to be in the kitchen.
I still believe you can not advance the tech at the rate it has been advanced and not support repairs after the warranty period or not train independent techs.
Mike cancelled many techs certification based on the fact they were out of date, but never fulfilled the plan to build a course and get the cert program back on track.
Sure, smart people can reverse engineer to a degree, and gain insight primarily by sharing info on a public sight like this.
But in the end, you can chase Lionel problems for many hours, almost fully disassembling a engine and its complicated wiring harness, only to found out later the new part received was defective and so was the batch. Or spend half a day doing a repair that really is only a 2 hr job. That is uncompensated time, because customers should not have to be billed that way.
The MTH architecture is common and more simple. Plus as an ASC, if I ask about a symptom I see for the first time, I can get a tech answer in 1-2 days. Not only that MTH has kept their tech document up to date and continues to shoot out tech updates on new issues found, etc... I rarely have to order a part from MTH for a repair. I can stock all the necessary boards and parts to repair 90% of what I see. I only order parts when I hit a low inventory on an item.
Since the advent of LC and Legacy, almost every Lionel repair requires a parts order from Lionel, and in many cases you have to get an RA, send back the old part before you get the new part. This is far more complicated then going on line an ordering as usual. I can't stock every Lionel smoke unit type, or motor driver, nor can I load the required software for LC or Legacy.
My opinion is that it is not a good business practice, but you can defend it. It is what it is. So I just screen the issues with customers that ask me to do Lionel repairs. So they have some insight what it may cost, and how long it takes. G
