Hello everyone, I had my subject units working okay and I don't know what happened but I can get my cab one L to respond with it's throttle but I can't get the TPC 300 to light up, green and run the variable voltage? Seems like I can't get power to get to the TPC. I tried a backup TPC that is new and it won't work either? Please advise what you think the issue might be and what I can do to troubleshoot. Thank you very much, well appreciated, Jerry
