John, Just got my booster hooked up to the layout, I have been away for a while, so I don't know if this has been brought up before. I have a two rail layout and with the booster hooked up I have both the green LED and the red LED lit. Is this an unusual happening? Tried operating for a short time and things seem ok but I am wondering if this tells of a problem.

Green and red? Are you sure you're not talking about the blue power LED?
What are you using to drive it, the original TMCC command base, or a Legacy command base? The older TMCC command base doesn't put enough signal out to get the green signal indication. If you're using the Legacy command base, it's not putting out a full amplitude signal.
John, I am using a Cab 1l system, I attached a pictures howing both red and green illuminated.
