Question about Chevrolet Silverado 1500

Brake contoller showing 4 volts on the connector pin all the time

I have a 07 chevrolet silverado 1500 that came with tow package. I took it to the dealer and had a brake controller installed. The pin on the connector for the brakes shows four volts all the time, even with the truck off. it does not change when the brakes are pressed. I am worried that it will keep the brakes on my travel trailer engaged all the time. Is the constant voltage normal? this was the second controller that I got. I wired the first one and had the same problem, so I took it to the dealer.

If the controller uses a SCR to switch the power on to the trailer brakes there can be some low voltage leakage across it. If you measure the amperage I would guess it's milliamps.

Call the dealer and tell them your concerns so that they may troubleshoot and correct the problem. They should have checked it themselves to insure they did a proper job.

SOURCE: Constant voltage on brake controller pin at connector.

you should not have voltage unless you apply the brakes on the vehicle or the brake controller. the only constant voltage you should have is the charge line on the 7-way.

Truck won't shut off until I unplug my tent trailer? Just pick up new trailer and had a 7 pin connector added to my truck along with a brake controller


It sounds like someone messed up to me! Apparently, the brake controller got wired into an ignition circuit that it should not have gotten wired to. When accessories are added to a vehicle, it is extremely important that the vehicle wiring diagrams are used so that you know EXACTLY what you are tying into. Some of the Chevy trucks that are sold with trailer towing packages already have the wiring for brake controllers under the dash. This makes installation easy and is already tied into the correct things.

2003 Silverado one ton shows -11.7 volts at brake lamp connections. Truck light work ok but the trailer brke light are leds and they don't handle the -11.7 volts.


Hello! Place a 1/4 watt, 50 ohm resistor in series with the +12 battery feed to the trailer LED brake lights...Each LED drops 3.6 Volts...You can run a maximum of 3 LED's per resistor...If you have more than 3 LED's run them in parallel with each set of 3...Each run of 3 requires it's own 50 ohm resistor...
