WOW, that is unusual for sure! Just wondering if you checked the AC noise on the 30V part of the RSL comm link? Can you read the end of line resistor on the car link? It's there to eliminate noise and interference. It sounds like your car link is possibly what's causing your chaos. Have you checked the traveling cable? Are you able to run the car at all on controller inspection or cartop? Sorry if this was already asked but I would step back to basic operations at this point to eliminate or to prove out any basic controller functions.
