No problems in 1 year, and the circuit breaker hasn't tripped, so I guess it is fine. Sort of hard to tell with a circuit breaker. :-)

I INSTALLED THIS IN PLACE OF ORIGINAL CIRCUIT BREAKER, ON OUR 2015 NASH 24H TRAVEL TRAILER. THE ORIGINAL TOOK IN WATER AND FAILED. I MOUNTED THIS POLLAK CIRCUIT BREAKER INSIDE A 6" LONG PIECE OF 1 1/2" ANGLE, AND IT WORKS PERFECTLY FOR THE SITUATION. THANKS VERY MUCH




by:

Product received on time. About 5 days since I live in NW. Electric brake installation went very good after watching install video. My trailer had a four way flat cable. I converted it to 6 way because my 2007 Winnebago View on 2006 Dodge Sprinter had the 6 pin. After hooking everything up my brake lights didn't work. The running and blinkers did work. I did a bit of research online. My View has a 3 filament rear light system meaning the brake and blinker have their own circuit. My trailer and most out there combine the brake and blinker onto one circuit. So basically it's a 2 filament system. Bottom line: going from a 3 to 2 filament system you need a "tail light converter". I added the converter into my RV at the hitch 6pin round connector. It was wired the standard way as 6 pin go. The brake output wire labeled X or S on connector was removed and added to brake output line of converter. My converter had 5 pins on input and four on the output. White being ground on both side, brown is running lights, yellow as left turn and green as right turn. The converter basically combines the brake light and blinker functions onto one line.
Once I installed the brake controller this wire run from controller to hitch. I connected this side to S or X where I removed the brake light wire earlier. So now my electric brakes work on my trailer as do the brake lights.




by:

I received the Pollak Circuit Breaker in good timing. The mounting bracket was mounted at a 90 degree angle from how it was advertised, but there was still plenty of room on my camper trailer frame to mount it. It works great! Fixed my converter for $10. including shipping.

Bought as a spare for stock.

  • After Replacing 30 Amp Circuit Breakers, Circuit on Trailer is Not Working
    If the item drawing the power is shorted or otherwise drawing more than 30 amps of power, the circuit breaker will trip and not allow power to go though it. So, you will also want to make sure that you do not have any wiring issues drawing too much power on the breaker.

  • Does a 30 Amp Auto-Reset Breaker Have to be Mounted or Can it be Loose
    You don't have to mount the circuit breaker such as # PK54530 if you don't want to. It would prevent it from moving around if it were mounted but won't affect how it works. So your plan of leaving it "loose" and wrapping it up in electrical tape will be fine.

  • Replacement Brake Release Handle Needed for the Husky Brute Electric Trailer Jack # HT87247
    The only thing special about the included circuit breaker is that it has some wiring included with it for easy splicing. Any 30 amp circuit breaker that you would find at a local electrical/home improvement store, like part # PK54530, is perfectly acceptable. If the jack hasn't been used very much and the switch wasn't allowing you to operate the jack then that leads me to believe that the battery that powers the jack has been depleted. If the battery is in good working order then the...

  • Adding 12 Volt Power to the 2005 Dodge Dakota
    What you need to do, assuming you do not have the factory 7-way is run a wire to the battery through a circuit breaker such as # PK54530. If you have the factory 7-way and are having an issue with the fuse box you will need to have the fuse box looked at by a mechanic. You can test your 7-way by running the power wire to an accessory 12 volt to see if there is any problem with the wiring itself. If you get power that way you know there is an issue with the truck's wiring that you will need...

  • No Running Lights On Boat Trailer But All Other Lights Work
    The first thing you will want to do is test the running light pin on your trailer side trailer connector. If you don't have power here then you know you have a bad fuse most likely. If you do have power on the running light pin for the trailer side trailer connector then you can move onto the trailer. The first thing I would check is the ground for each taillight but if this still does not resolve your issue then you will need to trace the running light wire from each light up to the trailer...

  • Troubleshooting No Trailer Running Lights with 2017 Ram 1500
    If the trailer running lights circuit isn't active on the 7-Way of your 2017 Ram 1500 then you will want to check the 20 amp blue fuse located in the F29 position inside the power distribution box under the hood. The online version of the owner's manual for your Ram shows this fuse as being in charge of this particular circuit. If replacing the fuse does not resolve the issue please let me know and I will be happy to look into this further.

  • Troubleshooting Blown Fuses on 2018 F-350 After Adding Lights to Trailer
    Thank you for all of the details! Adding 16.66 amps to your trailer tow lighting module could definitely have put it over the top since you added lights to what already existed on your trailer. If you don't plan on using that 12V power for a battery charge then there isn't any harm in using that to power your lighting. You can run it to the Upfitter switch if you want but my only hesitation with that is if you forget to flip that switch and then your lights don't come on like they need...

  • Can a 30 Amp Fuse be Used Instead of a Circuit Breaker When Installing a Trailer Brake Controller
    You can use a 30 amp fuse if you wanted to. The difference is that a circuit breaker like # 38630 or # PK54530 will automatically reset should there be a short or overload. With a fuse you would have to replace it.

  • Brake Controller Recommendation for a 2006 Monaco Diplomat
    The most popular and reliable proportional brake controllers we offer is the Prodigy P2 # 90885 from Tekonsha, which you referenced. We do not offer a quick-connect brake controller harness for use with Roadmaster chassis-based motor homes so your installation will be a hard-wire application. I did a little research and found that there should be a blue wire underneath the dash area that will be your brake output wire that will be run to the six way of the Monaco. You will connect this...

  • 2001 Monaco Diplomat Motorome Brake Controller Wiring
    If there is a brake controller port on the 2001 Monaco Diplomat, we do not sell a harness that would allow you to just plug a brake controller straight into it. If the trailer has a 6-way connector present now then it has some sort of tow package on it. I did a little research and found that there should be a blue wire underneath the dash area that will be your brake output wire that will be run to the six way of the Monaco. You will connect this brake output wire to the brake output wire...

  • Troubleshooting Brake Controller With Low Voltage
    You will need to find out if the issue is on the brake controller, truck, or trailer. To test the brake controller, sever the blue wire a couple inches from the back of your controller. Then use a circuit tester such as # 40376 to test the end of the blue wire coming out of the controller. It should only have power when you apply the manual override; if it shows power at idle then there is an issue with the controller and it will need to be replaced. The next thing you will want to do...

  • How to Determine Circuit Breaker Amp Rating for a 2018 Venture Sonic 200VML
    I can help you figure out what your circuit breakers are rated for but unfortunately I don't know what circuit breakers came on your 2018 Venture Sonic 200VML. I can say that we typically recommend using either a 20A or 30A circuit breaker for the 12V power so if your manual says 30A then I would tend to lean that way. You can be 100% certain by disconnecting all of your wiring and removing those covers on the circuit breakers you should then be able to tell the rating as the circuit breakers...

    You should have four wires coming out of the back of your Tekonsha #9030 Voyager Brake Activator, part # 39510. They should be white, blue, red and black. The white wire is grounded. The red wire must tap into the cold side of your vehicle brakes. The blue wire will run to the trailer connector on the back of your vehicle. The black wire must run to your battery to power the brake controller. If your trailer has 1-2 axles, use a 20 amp circuit breaker, part # PK54520, for this power...

    No plug-in brake controller wiring is available for your 2008 Jeep Grand Cherokee, but luckily the P2 brake controller # 90885 includes a pigtail that you can use to hard wire the unit to your vehicle. White: Ground, attached to the vehicle negative battery terminal. Black: 12v lead, attached to the vehicle positive battery terminal with a 20amp or 30amp circuit breaker, parts # PK54520 or # PK54530 respectively. You would use the 20amp breaker for a trailer with 2 to 4 brakes, or...

  • Installation of Power Wire to Brake Controller and 7-Way Connector on Motor Home
    The connection you will need to use is most likely the chassis connection in the case of the brake controller. You will want the connection that is hot at all times ran to the brake controller so that the trailer brakes can be operated at any time whether the ignition is on or not. The brake controller should be wired through at least a 20 amp circuit breaker, item # PK54520, and a 30 amp circuit breaker, item # PK54530, if the trailer has more than 4 brakes or the brake controller calls...

  • Adding an In Line Fuse to a 12 V Power Lead from a Vehicle Battery to a Trailer Connector
    I assume you are wanting to add an in line fuse to a 12V power circuit running from your vehicle battery to the trailer connector on your vehicle. There are a few things to consider before adding an in line fuse to a 12V power lead to a trailer connector. If your vehicle currently has a factory installed 7-way trailer connector, then the power lead will already have a fuse. If you are adding a 12V power lead to your vehicle, then we typically require a 40 amp circuit breaker, like part...

  • Voyager Brake Controller Does Not Light Up when Trailer is Connected to 2002 Toyota Tundra
    When a trailer is connected to the tow vehicle the Voyager brake controller # 39510 should show a green light. If it does not then we need to figure out if it is the controller or something else. First, to determine if the brake controller is the problem there are a couple of tests you can do. You will need a circuit tester such as # 40376 or a meter if you have one. Have someone sit in the truck cab and fully apply the manual override lever on the brake controller. At the same time test...

  • Brake Controller Does Not Power On After Installation on a 2002 GMC Sierra
    It does sound like you have everything hooked up properly and all of the connections under the hood are there so the only other things I can think of are a blown fuse (the green one) or a break in the wiring from that positive post on the fuse box to the brake controller. If the post does not have power as you have indicated then its connection to the battery must be broken. You can bypass it by connecting the power wire to the positive battery terminal via a 30 amp circuit breaker such...

  • Brake Controller Wiring Functions and Where They Need to Install
    The generic wiring guide in question just tells you the functions of the wires: white is ground, black is 12 volt power in (this is the wire that gets the circuit breaker), red is input from the brake switch, and blue is output to the trailer brakes. The white ground wire needs to be attached to the negative battery terminal. No other location is sufficient enough. The black wire attaches to the positive battery terminal via the circuit breaker although I recommend a 30 amp breaker, #...

    If your van has a round plug with a cap inside the driver's side frame rail you can use part # 30955 to complete the 7-way installation. This combination 4-pole/7-way trailer socket will plug right in to the round U.S. Car Connector if present. The blue brake output wire will already be present; it runs from the 7-way up to the dash near the emergency brake pedal. The blue vehicle wire connects to the blue wire on the P2. The white wire on the P2 is ground and connects to the battery negative...

  • Should Fuse be Installed on Power Wire when Hardwiring Brake Controller on 2006 Jeep Grand Cherokee
    It all depends on how the brake controller is installed. On vehicles that have a factory tow package that includes a plug or port to plug in a brake controller the circuit does have a fuse. If a brake controller has to be hardwired in then you would run the power wire to the positive battery terminal via a 30 amp circuit breaker # PK54530. But you could use an in line fuse instead if you wanted to. The instructions for the Primus brake controller # TK90160 mention to follow the generic...

This pigtail harness is 34-inches long, long enough for most installations. The black and blue wires on this part are 10-gauge and the others are 12-gauge; butt connectors...

    A brake controller does not have to be tied into the computer on your 2007 International 4200. A brake controller such as # 90885 requires 12 volt power in to power the controller, a ground which is usually attached to the negative battery terminal, an output wire (blue) goes to the trailer connector, and a connection to the cold side of the brake switch to tell the controller when you are stepping on the brake pedal. If your truck has air brakes then it is possible that there isn't a...

    Your 2017 Mercedes Sprinter 2500 may actually have brake controller port or wiring harness that you can use to install a brake controller. I have included a link to a video that may help. It is on a slightly older Sprinter but can be used as a guide. The 2006 to 2018 are part of the same generation. If the van has a third brake light (CHMSL: center high mount stop lamp) and it is the only thing on that fuse you could use it to attach to the red brake controller wire. The white ground...
