I'll be starting the build of my 310 in a couple of months once it shows up in its crates, and one take-away I've gotten from reading build blogs and threads is that it's wrong to assume that the factory did even basic stuff correctly in terms of connecting up the electricals. That sure makes it tough to diagnose problems since my first assumption would be that I screwed up something during the assembly. I'm curious if these issues such as incorrect pin wiring, connectors not connected, etc. are typical or if they're just more apparent because they get mentioned when folks run into problems.
