Some where along the brake output circuit, you have an open connection or a bad ground. The most likely cause is usually a corroded or damaged trailer connector on the vehicle or the trailer.
Turn on the truck and have someone in the truck. Touch one lead from an incandescent circuit tester like # PTW2993 to the ground pin on the 7-Way and touch the other end to the brake controller pin. This should complete the circuit and the brake controller should read as though a trailer is connected,... view full answer...
Two red flags go up right away. The first is the grounds, and the second is the unused wire you have.
Improper grounds can wreak havoc with trailer lights. You do not have to run the ground wires to the trailer frame, but they do need to be run to the white ground wire on the trailer connector. If I understand correctly, you ran them to the white trailer connector wire and then also to the trailer frame. If you do not want to use the trailer frame to host the ground, there is no need... view full answer...
There are a few possible issues that could be causing the brake controller not to engage on your 2002 Chevy Silverado.
First, I would check to make sure that your stop light wire from the brake controller, usually the red wire, is connected to the correct wire coming off your brake pedal. Go to the point at which your stop light wire is connected, and test the wire with a circuit tester, # PTW2993 if needed.
You should receive a signal when the brake pedal is pressed and should not... view full answer...
Since your trailer brakes only work with the manual override, that indicates a problem on the red wire of the brake controller. This wire gets a signal from the brake switch and tells the controller when you apply the brakes.
The port for a brake controller on a 2003 Chevy Silverado is located in a junction box on the driver side on the floor towards the front of the truck. The port on the top row, second from the left is where you would install a connector like # 3015-P. The other end... view full answer...
When installing a 7-Way connector like the Hopkins # HM40975 on your 2005 Chevy Silverado 1500 you'll want to match up the wires by function instead of by color. I have attached a photo showing what the function of each pin should be on a typical 7-Way.
If you have been testing each wire and you aren't able to find all of your circuits then you likely have some fuses that need to be replaced. You can find out which ones you'll need to check by looking it up in your owner's manual. view full answer...
Even though the fuses are good, I do recommend that you start by checking the pin in the 3 o'clock position (when looking at the front) on your 2003 Chevy Silverado's 7 way connector. I would start just by making sure that the pin is free of dirt, debris or corrosion and clean it off as needed. Then, you'll need a circuit tester like the # PTW2993 in order to verify that pin is receiving power when the turn signal and brakes are engaged. If there is not power, the issue is going to be on... view full answer...
The issue may be that your 2001 Chevrolet 2500HD cab and chassis model has the plug for the brake controller, but the electric brake and power lead wires are not run for it.
If you are not getting power to your factory brake controller plug, you will need to connect the blue electric brake wire and red power lead wire under your vehicle hood.
First, you will remove the bracket in the corner that is closest to the driver to access the accessory fuse block. Once you reveal the fuse... view full answer...
First thing to check is ground connections. Check to see if you can find the ground wires coming of the 7-Ways and see if they are grounded properly. If it is a factory harness, it could run all the way up to the battery so it may not be a problem.
The next thing I would check is the fuse block in the engine bay. Factory tow wiring will have some fuses or relays for the system. If it is just the brake function that has gone out on the 7-Way, it is probably the fuse or breaker that provides... view full answer...
One possible cause for the trailer brakes becoming jerky after warming up could be that you adjusted the brakes while they are cold. It is recommended that the trailer brakes be warmed, by applying the brake with the manual lever for a short period while driving at slow speed in a safe area. Once the brakes have been warmed you can then adjust the controller for proper operation.
Other possibilities are that the delay could be set to long on your time delayed controller. Try setting the... view full answer...
You have a unique situation that I've never ran across before. So I reached out to my contact at Curt and he's thinking that the ground wire on your Curt Venturer Brake Controller # C74VV has power coming through it from the high beam switch of your truck. To test this he said to cut the ground wire and test the current through it. If it reads inconsistent then this is your problem.
He suggested using a diode (part # RM-790) on the ground wire, or replace the high beam switch in... view full answer...
It sounds like the harness you're using to connect your Voyager Brake Controller # 39510 to your 2002 Silverado 2500 is pinned-out incorrectly. The correct harness for installing the Voyager in a 2002 Silverado 2500 with the factory 7-way is part # 3025-P.
If you compare the photo of this harness' vehicle-side connector that I linked for you to the pin-out arrangement on your harness chances are you'll find that they are not the same. You may be able to change the pin-out of your harness... view full answer...
It looks like you've got a 2011 Chevy Silverado, and it's likely that you just don't have power on the wires you've connected the Pigtail Wiring Harness # 7894 to on your vehicle. If you haven't already, you should test the power wire to see if it's active when you turn the vehicle on. There are two wires under the hood that have to be connected to make the tow package functional, one is the power wire to the brake control and the other is the battery charge line to the 7 way connector.... view full answer...
The plug-in adapter you have on your Silverado is the correct one. We buy them in bulk so the number can be different, but I did verify that the harness you have will work fine.
You need to disconnect the plug-in adapter and find the vehicle side pin that matches up with the pin on the plug-in adapter connected to the black pin. use a circuit tester like part # PTW2993 to make sure you are getting power.

For the 2001 Chevy Silverado you should be using brake controller wiring harness # 3025-P. You will need to make sure that all of the wires in the back of the end that plugs into the truck are in the same location as in the picture I have included. If anything is different you will need to rearrange the wires, so they are in the proper locations.
If you still have problems, then you will need to test the brake controller to determine if it is the problem. In the truck cab you will need... view full answer...
I believe I know what is going on with your brake controller on your 2006 Chevy Silverado 2500HD. But first a note on brake controllers. Brake controllers are not vehicle specific. Some trucks do have an option to plug a brake controller in directly and the harnesses used are vehicle specific. But the brake controllers themselves are not.
Your 2006 Chevy Silverado is a model that can have a brake controller plugged directly into it. I do not know which brand brake controller it is that... view full answer...
The Fogatti RV Tankless Water Heater - Gas - Automatic Pilot - 41,800 Btu - White Item # LSB64FR has a minimum pressure requirement of 8" WC and a maximum pressure of 13" WC. Any pressure outside of that range will cause the # LSB64FR to not properly work. It sounds like you might need to replace the regulator since you can't run the stove and water heater at the same time.
Depending on your setup if you have a larger single tank you could need a vertical 2 stage regulator like the MB... view full answer...
A 3rd brake light, or CHMSL (center high mount stop light), like the one on your 2011 Chevrolet Silverado Duramax, is typically fused separately from the other lights. Check the lid on the power box for a legend that tells you the location number of the CHMSL fuse. Check this fuse then replace as needed and try again.
You can also check the orange wire under the dash. If this 3rd brake light wire is rubbing on metal it would cause a short and blow the fuse and prevent operation of the... view full answer...
Since you know the brake controller works when connected to stud #1 it should not be a brake controller problem. From what I have found, stud #1 is dedicated 12V power and a 40 amp fuse, you do not want to keep the brake controller attached to this. Troubleshooting this issue directly would require working with the fuse box wiring, which is not something I would recommend.
Instead, I recommend running new wire to the battery from your brake controller. Take the wire from your brake controller... view full answer...
The "Output Shorted" message on the Tekonsha Prodigy P3 Trailer Brake Controller part # 90195 indicates that there is a short on the blue brake output wire. If you just installed the brake controller then make sure you have the blue wire attached to the dark blue wire on the vehicle under your dash.
If the brake controller shows the error when no trailer is attached then you know the issue is on the vehicle side. That said you will need to check the trailer connector for corrosion but... view full answer...
If the lights on your trailer were acting fine prior to installing the LEDs then you need to start off by checking the ground connections for your lighting. Make sure they are securely connected to a clean, bare-metal surface as even some paint can cause issues.
If that doesn't fix your problem then the solution to your issue is to add load-resistors. I recommend the Diamond # DI34ZR.
Since LEDs draw less power than incandescent lights it is not uncommon to have to install load-resistors... view full answer...
