Tekonsha brake controller issue

I've had my tekonsha Prodigy for 4 years and have no issues till recently.

 

I had a Sloan Kwik-Load car trailer. It required locking the brakes to break the trailer over to load/unload the car.

 

What I noticed about 6 months ago was that I would manually engage the brakes and it would go to the preset "intensity" and then begin dropping off to about 1/3 of what I had dialed in.

 

It will also do the same thing when I apply the brakes ... the controller ramps up as normal, but won't maintain the brake voltage.

 

I tried all 3 ramp rate settings, each with similar results.

 

About the same time that this began happening, I had an issue with the trailer plug and replaced it with a new wiring plug.

 

I have checked the grounds and wiring and everything seems to be fine.

 

Since then, I have bought a new trailer and the problem remains.

 

I'm kind of against a wall here. any ideas on where to look?

I called Tekonsha Tech Support and they were kind of stumped as well. She told me the Prodigy (maybe all Tekonsha) has a lifetime warranty and I can take it to any retailer for an exchange. I thought that was pretty damned cool.

What happens when you stand on the brake pedal? If you aren't slowing very fast, creating the inertia, then the controller will send less and less power to the trailer. If you are slowing quickly and increasingly so, using the trucks breaks to create the needed inertia to signal the controller you are slowing in a hurry, then it will send more and more power to the trailer.

 

In other words the harder you stop the more voltage is sent, the easier you stop the less voltage is used.

 

P.S. On mine I have the boost feature set high, so the trailer breaks will grab pretty hard at first but as I slow down easily the inertia is less so the voltage drops lower.

try checking the voltage across the harness with a multimeter or check your fuses for a loose fuse if you can't get it to work right.

 

I don't have to much experience with inertial brake controllers so i may be talking out my A** but, its worth a shot

This includes trying to splatter your eyeballs to the windshield? If so I'd say there is an internal issue with the controller. Such as the pendelum that senses the amount of deceleration/inertia. Either way just get a new one no sense trying to fix the controller, especially if a replacement is free. Plus you have already eliminated the trailer as the culprit and I can't think of something in the truck causing this problem... (I think if the truck was the culprit it would either work or it wouldn't) At least Tekonsha is trying to stand behind their product.

My thoughts as well.

 

I went as far as to make sure the unit was level ... still no change.

 

I can't fathom anything the truck is doing to cause this. But one never knows ....

Sure enough ... I walked into a camping center, explained the issue, relayed what Tekonsha told me and they handed me a new unit.

 

d**n!

      My brother has an Escalade. The warranty has expired so he told his wife to go to the Valvoline quick lube he uses some times. They told her if her car was a 2020 and newer 6.2 engine they wouldn’t touch it. Hers is a 2019, so they did the oil change.

      2026 6.6 L5P oil cooler leaking oil at 4,000 miles

      The oil filter has NOTHING To do with oil leak. GM sources parts from 1,000's of vendors and as with anything mass produced, flaws are unavoidable.    Putting a larger oil filter will do nothing but satisfy emotions. The OEM filter is designed for the engine and perfectly capable of handling the demands on the engine. Oversize oil filter could result in reduced flow and overall lower oil pressure.

      You're better read than that Atlas. 😏   British science fiction writer Arthur C. Clarke formulated three adages that are known as Clarke's three laws, of which the third law – that "any sufficiently advanced technology is indistinguishable from magic" – is the best known and most widely cited.   Stribeck and the pivotable Hersey Number isn't voodoo nor snake oil. That part is physics. It's what marketing and bean counters do with it that is snake oil and voodoo.    Stribeck is the relationship between Hersey and the Coefficient of Friction. Within the Hersey Equation if viscosity and viscosity is 'Dependent' on.......heat.......and.......viscosity index or the temperature to viscosity slope.    Specifically Hersey is the viscosity AT THE TEMPERATURE IN THAT LOCATION FOR THAT SLOPE.   Hydrodynamic lubrication exist when the film thickness in the location is 3X the Ra roughness of the surface. This is irrespective of the hardness of the substrate. To obtain that thickness X viscosity is required for Y velocity at Z load. That's a lot of moving parts. It is also impossible to maintain in an ICE but nearly possible with a turbine under constant load.    What does that mean? Error heavy and operate light. Wear is inevitable but the rate of wear and the milage obtainable are a function of prevailing conditions and HABITS. The only penalty is viscous drag and at fractions so low as to be well worth the effort. Double the life, half the manufacturing carbon foot print. Greed is the only impediment.    The materials generated by SwRI are the RESULT not an estimation or a hypothesis.    Don't delude yourself sir, EV's have as many pitfalls as ICE's. We just don't know what they are yet and it will take longer to sort as MARKETING and GREEDY CEO's have had more time to polish the turd they are selling.

      You can always count on greed to prey on ignorance and stupidity.    Friend bought a 2019 Ford Flex and asked me about using Valvoline R&P 5W30 in it. Told him give the miles on it and the fact it wasn't yet using oil that it was a good plan. He uses a Valvoline quick change shop for his oil service.   First they tell him that isn't the oil the OEM recommends. He told them he didn't care what the OEM thought. Then they floated the, "But it will void your warranty"    His reply was it's a 2019, there is no warranty and informed them their knowledge of the law was lacking.    Then they tell him 'But it will ruin your motor"!.    Mine to ruin he says. Finally they give in and charge him 150% the semi-syn price    Point it the brainwash is so embedded that even the service industry is drunk on their swill. The public is right behind them. Echoing the same lies on every forum and media platform. If the end goal is indeed EV then I'd say that ship is about built.
