Right ok did you try the pantograph reset? will get it logged, a video would be helpful as well if possible showing it not doing it
When you move the power controller to off it'll dump all power and you have to wait for it to run down before you can reapply. The first black vertical gauge shows what tap you're in. The end of the video shows you reapplying power but you're only applying a very small amount, if you hold the trigger rather than tap it it should allow you to gradually apply more until you are happy with the amount. I'd recommend the tutorial and reading the manual which should explain this in better detail. downloads.justtrains.net/products/JTF003001/WCML_Preston_Carlisle_TSW5_manual.pdf?fbclid=IwY2xjawGy1O9leHRuA2FlbQIxMAABHR4VPyTNS0srmTuR8vJR8D6_14aYi-GEoBqlkFcwwOlrcarRz0-Mr5sBrg_aem_hV91Ifh0aSY0VUMAbLUTZQ
