I did a bit more testing on the decoder this afternoon and found that it will not turn on the main interior lights it should be F12. F11 turns on the cab light but at the cab at the rear. I have let youChoos know and I imagine it will just need a few CVs tweaking to fix it.

Probably the function mapping.

Or if they are LEDs possibly the +ve (blue) is wired to the wrong terminal (yellow/white) - I've done this before now :).

Hi Richard, I spoke to Digitrains the other day, and there is a "fix" to do , to solve this, Ill look at the instruction sheet later this week, where I plan to get them fitted, but more than likely someone will beat me to it.

Best regards
Craig.

Youchoos have identified the problem and are doing a guide to to how to fix it.

This is how to fix the cab lights.
The cab lights are the wrong way around because the Dapol leaflet has them listed the wrong way around! This is easily remedied with CV#129=1 and CV#130=2.

They also suggested that changing CV112 to 32 would improve running, I tired it on mine and it didn't make any difference to be honest, mine runs very well.
