hello, i just replaced the SX controller on a Yale ERC030AG serial # A814v05078x and now the line contactor kicks in and out rapidly as soon as i turn the key forward and does not stop until i turn the key back off. the dash does not display an error code when this is going on. what made me replace the SX controller was a Code 66 the truck was giving off. is this contactor "issue" a faulty controller or an adjustment issue within the SX controller? thanks, jay
