CV number for HO F7 A diesel

[keith beavis]

Hello,
I'm having trouble finding out the CV number of my Bachmann F7 A diesel.
I have 2 new engines, neither of which have any numbers on them.
The engine runs but will not recognize any other commands.
What is the CV number for this train.

Dear Keith,
The default address for all our locos is 3, irrespective of cab number.
Have fun!
