I purchased this diesel locomotive several years ago. Just this past week, I gave it
a test run. Unfortunately, it only ran in reverse in reference to the cab; no lights
either direction. I'm running with a MRC Controller.
Any suggestions as to where I start trouble shooting
Thanx in advance...

Just recently I came across a Spectrum Coach #3764 Item No. 89003.
I know it's very old and it could have been a kit.
I'm experiencing a problem attempting to replace the couplers[horn hook] with knuckle couplers.
Can anyone shed any light on how to go about this or is there a knowledge base to reference how to solve my problem.
Thank You in advance for any and all information that you can share...
