Wiring Installation of Tekonsha 50-85-313 Trailer Breakaway Battery Kit

Question

Question:

I am replacing a breakaway switch only on my camper trailer with the Tekonsha 50-85-313 kit. I decided it was better to have an independent battery for my breakaway rather than relying on the trailer battery to be charged all the time. The one thing that I did different than in your excellent install video was to use the existing power feed from the old switch rather than connect a new wire to the black wire of the 7 pole connector. The reason being is that I have a fully sealed 7 pole connector with no accessibility to the plug end. I do have accessibility to the wires in the middle where the plug is spiced into the wire from the trailer itself. That looks to be a factory splice based upon the way the wire is heat shrinked and very nicely done. The only thing I noticed is that when I put the battery in the trailer box, the battery in the breakaway kit immediately showed that it was charging. Is this going to be a problem and should I wire are you suggest in the video or an I ok taking bower directly from the trailer battery?

The Tekonsha Push-To-Test Trailer Breakaway Kit with Built-In Battery Charger - Top Load # 50-85-313 is a much better option for your Breakaway system than having the trailer house battery serve that purpose. The way you wired the 12V input to your trailer battery, you will still be draining your trailer battery as it seeks to charge the breakaway battery. Once that trailer battery falls below a certain point, you will then drain the breakaway battery to try to charge the trailer house battery.

This puts you almost back to where you started without the separate battery. I recommend running the wire as we show in the video and the attached diagram so that your trailer battery is completely separate.

First you will need to remove the old hydraulic equipment. Remove the surge coupler or actuator, remove all the lines, and finally remove the brake assemblies. If you have 10 inch diameter hub and drums, you may need to replace those as well. If you…

The Dexter DX Series #K71-651 and the Hydrastar Vented Marine #HS381-8067 are more comparable as they both have hardwire installations (just made by different manufacturers) while the Dexter BrakeRite II #T4813102 is more of a…

Hi Hayden; that bolt pattern is really uncommon but I believe it can be found on some really old Airstream trailers. There are no modern replacements that will match. The best option is to replace the hub with one that has a common bolt pattern like…

There really isn't a particular maximum trailer weight that is used to determine when brakes need to be added to both axles of a tandem axle setup. While I do still recommend checking your local laws, I am also not aware of any general laws that…
