Repairing A TST Sensor
Timely thread...my TST was indicating a leak in one of the tires and after hours of inflating, checking psi with tire gage, replacing valve stem, reinstalling sensor and still having the low pressure alarm repeatedly going off indicated 59pis I decided to check the tire psi with gage and it indicated 80psi the inflated amount. I discovered the cap had an O ring inside the top of the cap plus the one on the sensor...l also decided to replaced the battery.
So far (12hrs out) the tire is holding air. Interesting[emoji847]
