TST TPMS Repeater Wiring

[Rivet Rocket]

Going from a single axel (2 sensors) with no need for the TST TPMS repeater, to a 26 RBT that will have 4 sensors and 2 axels, so will be getting the repeater with 2 additional sensors.

Question for the many of you that use this system is how/where to you mount the repeater?

Second question is how do you wire it to the battery(s), also going from 1 acid battery to 2 glass matt batteries?

Last question, if left hot with no shut-off switch, will it drain the batteries any worse than the propane detector? Does the repeater have a sleep mode that it goes into after a period of no activity?

Thanks in advance for your insights and expertise.

I have a Tire Minder system complete with a booster. I mounted the booster in the battery box and wired it directly to the battery so it does draw constantly but I also have a solar system that is on all the time so it does not have any negative impact on the batteries. You can wire yours to a hot wire that is controlled by the main battery switch and avoid the drain issue. The Tire Minder System has not been trouble free and is actually a pain because something is always going wrong from bad sensors to a bad main monitor. I would now not recommend the system although I sure found it helpful when it was working. Booster has been flawless. Jim

I mounted mine on the battery box and hooked directly to battery. I am always either on shore power or towing so battery drain is not an issue.
I also have TST and it would work without repeater unless I had my Garmin RV 760 on the dash and it would keep the TST from getting a signal to the monitor. No problem after installing the booster.

I mounted my rear camera repeater and TST repeater in the battery box. Hot wired directly.

I tow with an SUV. I tucked the repeater under the edge of the headliner next to the rear window. I power it from an already-present 12V power outlet, and plug/unplug it manually.

I have a 25FB and I found that the TST 507 external units on my trailer are detected by the receiver even without using the repeater. I use the repeater anyway because I already have it.

I have a 25' flying cloud with a TST system without a repeater and it works fine. You might want to try using it without the repeater first and if it works ok you can save yourself the trouble of hard wiring the repeater to the battery.

Although you didn’t ask this question - we found that a repeater was unnecessary for our FC 30.

First I'd try it without the repeater.
Then you have a couple options. Mount it on the trailer or on the TV. How about outside the propane cover, or in the back window of the truck?
I'd make a way to disconnect it so it does not drain the batteries.

Here is how I mounted mine-have the new color monitor-great TPMS from TST.
Easy process.
Inside the Propane cover with velcro.
Wrapped the wires around the tank holder in case the velcro failed(unlikely but you never know).
Wires out from bottom of the propane cover and through the hole already there in the battery compartment.
Attached small battery clamps bought at auto supply store.
Easy to attach/detach if worried about battery drain.
Works great.

When we bought our TST it would drop one or more tires right at about 50 miles into the drive but not in a pattern and it did it on both trailers. I sent it back to be checked out and they replaced the head unit. I've been on several trips in the 28' since then and it has worked perfectly each time without a repeater. It now will pick up both trailers when parked and the Minuet is over 100' away in the back yard.

I have several friends who have them on larger Airstreams without a repeater and they work fine. Try would it first without and see if it works before you go to the trouble of installing one.

Hi All,

Thank you for all the great responses. I would wire the repeater right to the battery in the front of the trailer, Red Wire goes to positive, Black is Negative. Some use alligator clips, other wire directly to battery. Either is fine. Once the repeater has power it will glow red, and flash occasionally. The repeater has an in-line fuse, and draw is very low(a few milli-amps). Once connected just close up the battery box, and no need to worry about it.

As always if anyone has any questions I am always available at 210-420-0132

Thank you!!

PS: Our new Full Color Wide Screen Display is becoming very popular in the Industry, it does work with all existing 507 sensors.

As the OP thanks to all that responded, great ideas and solutions.

My 22 FB had the exact conditions that RVB listed and I figured it was dropping the signal with no repeater. Therefore the decision to buy the repeater for the 26 RBT.

Will try with the repeater in case it is a defective head unit, signal will still drop after a short drive and I can contact TST.

Good to see that the National Sales Manager for TST reads these threads, they make a great product and care about their customers.

As the OP I was pleased to see you post. Ordered the additional parts from Peggy in your office yesterday. Shipping confirmation today and she also sent a PDF of instructions as she promised. Well done, excellent service.

I mounted ours on the power jack and ran the wires under the frame and got power from the same wire the power jack is getting power from. Make sure you install a fuse in the line. Lots of places for ground wire to attach using existing bolts.

Previous truck had it wired into the "running lights" at the rear of the TV. I then placed the repeater on the back of the turn signal assembly. Worked perfect for 4 years... and only 'ran' when I had the lights on... like when I am towing.

Our Doran TPMS made the transition from a single axle 22FB to a dual axle 27FB without the need of a booster. Just ordered 2 new tire transmitters for the 2nd axle and reprogrammed the receiver.

I have 26u, and I mounted the repeater in front trunk compartment and pick up the power from the light in that compartment. I grilled small hole into bottom of light and wired into power source of the light. The repeater is on all the time

[dmartinez]

I have International 25FB with lithium batteries under my bed. Contacted TST they suggested I install outside my trailer. As a result I am going to tap into power jack wiring and mount under frame.

FYI: My unit came with a warning to install the repeater, if not used may void the warranty.

I have the TST color monitors for both my 2017 25FB and 1968 Caravel 17. I purchased the repeaters but haven't installed them on either trailer.

My monitors easily reads the tire sensors. Perhaps it works well for me because my RAM 2500's dash is higher than most TVs. I did use it with my lower sitting 2012 RAM 1500 and 23D. I mounted it inside the 23D's propane cover and directly wired to the AGM battery.

As a full time phantom draw I've wondered how much power it consumes. Perhaps it could be switched.

Ford Excursion/ProPride/28’ FC: no need for relay. Works fine without it.
