These are burning pretty bright, not at 100% but about 85%. I agree that someone inside of the chassis node whatever that is is where my trouble lies.

Yeah the old days of wire going to a switch then to a component are gone.

Now we run a wire to a switch, then to a module of some kind it then decides what to do and sends a signal to a relay or something then a wire to the component to make it function.

Progress is killing us.
