Only 6.6 volts coming from 14' factory brake box
As the title says a 2014 f150 with factory trailer pkg. Only getting 6.6 volts at the truck plug and 6.6 to the breaks on the trailer. Truck isn't putting out the 12 and relays and fuses are good.
Ideas?

What's the gain setting? And is the brake fully depressed? I would think the level of braking would depend on the voltage and the 2 factory contribute to the amount of braking.
Also, not sure if you even be able to get a correct reading without the truck recognizing the brakes are hooked up.

Are your trailer brakes not working?
