Roco Br146 Reversed Light Aspects

[brickfan3341]

Hi all, I am trying to chip a Roco Ho Br146 with a Lenz Gold decoder.

On checking the Loco prior to inserting the chip I have noticed that on DC operation the red lights operate in the forward direction and white lights on the rear. 

The loco was second hand and had no blanking plate fitted which i have replaced. there is also a small 3 port plate on the circuit board which has a wire jumper fitted.

Can anyone see an obvious issue or suggest a remedy?

I'd guess the jumper wire might be "track" or "overhead" (pantograph) power.   

 

If its just the red/white seem reversed, then the simple fix would be to program the decoder so the lights change round.   CV33=2, CV34=1 .

OK. I will give that a go. It will be my first go at altering CV settings.
