Hi:

The Yard Boss tender came with these parts:

The contacts fell out.

I can't figure out what the 'contacts' are for, or how the fit on the truck along with the wheels. I can't seem to find any photos either, esp. photos that show which way is up for these contacts.

Any help would be appreciated.

Thanks,

David
