Lee,
Sorry that wasn't much help.
You might try doing a complete by the manual start up of the locomotive,
and making certain you have a hot battery  in place and all the switches
where  they're supposed to be, if you haven't already.
I'm not certain of your location, so can't make a recommendation of someone
local or nearby who might be able to offer assistance in real-space.
Maybe someone will chime in with an answer for you.

Dave
