While operating this morning with Legacy, we had a car off the track and some sparking. Suddenly the control no longer worked and all three base lights, red, yellow and green are on and we have a base not found message. We tried to reset the channel but the yellow light does nothing when the button underneath the base is pushed. It does not wink out a channel number. The manuals are very hard to trouble shoot with. Any help would be appreciated. Bill Park

It's highly unlikely that a derailment resulted in the issue with your command base or a lot of us would be seeing base failures.  The legacy command base output to the outside rail has a lot of protection, capacitor isolation, a number of inductors, not to mention a 100 ohm resistor to ground after the cap.  It should be pretty effective protection from what happens on the track.

Hi John, Thanks for your help. Do you have an idea what the three lights lit on the bottom of the unit mean? Is there a manual I can look at to gain some idea what to do? Does Lionel have a person I could call for any help?  thanks, Bill

The yellow light is used when you're doing special functions like changing the channel, etc.  All three lights steady on suggests that the command base is hung in power-up initialization.

The only thing I can think of is to stick a base update module in it and power it up holding the channel button and hope it reloads the base software and gets it's mind right.

Gentlemen, Having friends is a great thing. I do not have the modules to reload the program. I placed a call to my train club buddy here Don Klose. Don told me to him my base and he would let me take his spare base. He said he will reload the program for me. We have a large train group coming to my house at the end of the month and Don is going to operate the Legacy. I am hoping there is nothing wrong with my base. Its great to have friends. Bill
