Now it's staying at 280ish, which is incorrect, it should be around 400. DI ST 4 on Tycom also says temp should be around 400. 4) TC seems to have issues. TC on S showed up "b", Jim McVittie disconnected and then reconnected TC plugs, and it went away. But now, "B" shows up on another TC: TC L. I attemped same thing, and it went away, but I think temp reading is still wrong. Other Info: I noticed all this as I was loading the boat, after cooling the furnace down from 800 to 400 (I need to load at 400).
