light on loco stopped working

[Ellobo]

The headlight and tender light on my Mogul 2-8-0 with DCC & sound stopped working mysteriously.  Is there a way to turn them back on?

Hi Ellobo,

Did you check that the headlight is turned on using function 0?

[Ellobo]

yes

Could be a defect in the plug between engine and tender. Jiggle the wires back-and-forth and see what happens.
