Last week I purchased a 2021 Premier Big Boy Restoration (20-3807-1). After running it a few times it will no longer start and the MTH DCS controller doesn't recognize its presence on the track.
Despite running it for less than 10 minutes total I have had to add/remove it to my track several times so other replies in this forum RE: "Check the 4 pin mating tether socket to mounting PCB solder joints. They are known to get cracked from the tether being plugged in and out or jerked on." sounded right to me.
I replaced my tender with one from my J-1 2-10-4 and to my surprise the Big Boy is back up and running.
What should I check for in my Big Boy tender?
