The short Tether on my MTH Diesel A-B-A seems to loosen after running about 10-15 minutes causing the trailing unit to lose motor power, and the front unit to attempt to drag it. Lights remain lit in the trailing unit when this occurs.
They are running on a layout where the smallest curve is 080. Pushing the short straight tether cable all the way back into the socket restores power. This is happening on a SF PS 2 A-B-A set (20-2258-1) and also on a DL-109/110 A-B PS 3 set (20-202228-1). Any suggestions to remedy this will be greatly appreciated.
Thank you,
Ron
