Hi Clive,
Do you know how to access programming track mode on your Power Cab? If so, read the value for CV29. If you don't, do the follow to access and read CVs from your Power Cab:

DCC is not easy, obvious or intuitive. A beginner DCC book from Kalmbach would not be wasted money.

First of all welcome to the forum. Your posts are delayed in moderation for 5-10 posts or in my case, for life.
The above link is for OO scale but it also comes in O scale. Scale should be irrelevant.
If the wires from decoder to motor are hooked up backwards, this will happen.
Internet "Science" will tell you that changing CV 29 will correct this or not, it will just make the problem exactly the opposite. I have never experimented to find out. I suspect the later is correct.
CV29 is a multifunction CV controlling speed, DC capability, long or short address and direction of travel. There is a calculator https://www.digitrax.com/support/cv/calculators/
It's quick and easy I would try it. If that fails I would switch the motor leads on the decoder.
Which lights go on and off? British locos have rear marker lights the on the models come on. The headlights and on some models the head codes comes on in foward with markers on the rear. Is it that your markers on coming on but not the headlights?. maybe the headlights need to be turned on.

Hi,
I am new and Hello to all.
I am useless in the use of Power Cab V1.65
It serves a purpose to run 9 GWR Steam trains.
But I needed a Engine that can clean the tracks well by having the grunt that my Hornby Engines do not have.
Ok I got a Heljen Diesel Model 26 to haul the track cleaner.
But one fault.
It goes forward and the rear light comes on. Go back and the front light comes on.
So the Lights work opposite to the direction.
And I can not find the answer. Being slightly of age and useless in computer skills.
Any help would be appreciated.
