Troubleshooting is a skill. I don't know how exactly it can be taught, but we should absolutely be teaching it.
I have never used a scissor lift in my life prior to this point but I know enough about machines now to realize something is wrong. And with an error code, the machine will tell you what's wrong.
It's up to you to connect these things together - and that's honestly a guiding light in my work.
@TechConnectify It would be pretty cool to have a 'diagnostics' class in school, which would just focus on identifying problems, lol.
