hello-

my son pulled off the front wheel set of a 'santa fe' engine that came with an old Bachmann set.
i took off the plastic housing. a couple of the wires are now detached. there are red, black and green wires attached at 3 points (i believe it's 3 - i don't have engine in front of me right now) . it's a pretty simple wiring set up but i don't know which wires go where. is there a simple diagram out there so i can solder the wires back in the correct configuration?

thanks in advance for any help!

jim
