Hi guys. I recently purchased a 3000w 72v motor kit and it came with the SW900 Display I asked the seller what displays are compatible and he said the UKC1-18 is. So I purchased one of those and there's no throttle input at all everything else looks like it's working apart from throttle but I don't have a PAS installed any ideas on what's wrong? I also checked the settings and there's no drive mode option thanks for any info.
