Hi.
I have an old loksound v4 with a Paxman Valenta sound file.
Not sure who's sound file.
Problem.
When I power it up it gives thrash but within a few seconds it drops off then starts to thrash again, all with the throttle fully open, it just keeps cycling like this on full throttle and its doing my nut in.
The sound file is great but try as I may I can't get it to keep thrashing in relation to the throttle position, it just continues to drop off then thrash again.
I'm not too clued up but I'm average, I use a Z21 black and JMRI on a laptop to tweek CVs.
Any help would be much appreciated
Kind regards Phil
