There was a loose coax cable in the wiring bundle in the front area, but not connected to the tire sentry display. After doing some research on Tire systems I concluded it might be a cable for that. When I took the shell off the display unit I could see a red led lit on an inner pc board, but the display is dead. In most systems I see for sale the transmitter is only needed when there is a long distance to a tire sensor. Where would the transmitter sending unit be located. I did connect the cable with no results. I did check and replace the wheel sender batteries.
My documents have manual on most other things, but none on the Tire Sentry System. I did find some information on it on a web blog. I might be interested in upgrading it, but since Tire Sentry Systems will not respond I would find another vendor for a system. Thanks
