This is a problem I have had since I picked up my coach at the CC factory on 12/1/04. Approximately two to two and one-half hours after getting underway each morning, the Silverleaf loses the signal from one of the SmarTire transmitters. Then within the next five to ten minutes the signal from all transmitters is lost. Since I usually get underway around 9:00 am, this usually occurs around 11:30 am. When we stop for lunch (usually around 12:00 Noon), I turn the engine off and following lunch when I restart the engine I regain the signals from the SmarTire transmitters and they then work for the remainder of the day. The remainder of the day is usually three to three and one-half hours. This problem has been looked at twice by Les Schwab in Junction City, but no solution has been found. Many of the SmarTire transmitters have been replaced, the SmarTire "brain" has been replaced, the rear antenna has been moved farther to the rear of the coach, and the Silverleaf brain (the PM-002) has been replaced. I still have the problem each and every day. Of course, it is almost impossible to get anyone to REALLY look at because when I arrive at Les Schwab's the system appears to be working correctly, and NO technician wants to get in the coach and drive it for two to three hours to make the problem appear. Does anyone have any ideas? Brian Davis 2005 CC Intrigue LE 42' Ovation Triple Slide Coach #11901
