Have the TST507 tpms system. when traveling, not all the sensors show up. I have a 30ft 5er. do I need to install a repeater, and are there different brands
We have the TST 507 system also. The sensor for #1 axle right side of 5 ver was not working. 2 year old system. I had trouble finding 1632 batteries in socal. When I got home I pulled the sensors and all batteries read approx 3 volts except the bad sensor read .9 volts. Replaced all batteries and all is great again. BTW 1632 Duracell batts at Safeway were $5.99 each. Ordered 8 online to carry for next time.
