    Hey guys, How are you all? I have a RTU that won't ignite. I changed the ignitor board, and a ste up, crazy leg transformer (120v pri & 230v sec). The only things after thar are the UCP board, gas valve, glo plug & roll out. Please HELP!!!

    What I/C do you have Texas or Fenwall?
    Whats your cold ohms on HSI?
    What voltage are you getting to HSI?
