Hey guys back again. Tuning up the next car and im having an issue with io’s flickering. Only the ha monitor io’s are flickering on port 12. I ordered a can repeater but theres another car here that doesn't have a repeater with no issues. All hns are online. No faults. 60hms on hcl hch. Prints call for a repeater but none on site. Also, theres no hoistway access for the bottom since its a walk in pit so i jumped a breakout board on the bottom hnb since theres ios for it. Tried a regular hn on the bottom but would not teach . Any info is much appreciated
