Well it is done. My first Decoder install on a "Bachmann Trolley Lighted" Everything worked! :) It was a lot easier then I thought it would be. It took about 20 minutes. Runs great!
One of the things I would do different the next time is to cut my wires a little shorter. I did not want to do this on the first one in case I messed up.
I have also learned a lot about resistors and and choosing the correct decoder.
Now to order more decoders. A lot more engines to do and a few lighted cars.
Thanks to all who helped along the way
