When I met with the Tire Minder people in Madison I was told they are now recommending two "boosters" for the longer tag axle coaches. We've always had one in the rear closet and have added one in a cupboard of the mid-bath.
We'd been having problems with false alarms until I got totally frustrated and shut down the system. While in Madison they gave me a new receiver and an additional booster. The system seems to be working fine now with the exception of a couple of the transmitters that are well outside the described margin of error for reading pressure. These are, however, first generation transmitters with five years and thousands of miles on them.
