After reading the first message that started this thread....he says he FREQUENTLY gets an over current message. Are you sure you are not getting a stinger from the center conducter and the braid. That will cause an over current situation. Suggestion, make sure your cable stripper is new and sharp. See if that stops the intermittent situation. Also I see that you make reference to Dishnet LNB's. Another suggestion, if you have the ability to keep an LNB on your rig at all times, keep one that does not give you an overcurrent reading. Use it to point and peak your system. Dish is notorious for LNB's that are suspect.
