Brake controllers like the part # 5504 can put varying amounts of voltage on the brake output circuit depending on how much braking power is chosen for the controller. When a controller is set at it's max braking power it will put 12 volts on the output circuit. Having a setting where 9.2 volts is put out would be normal. You could try adjusting your controller up the highest power setting to see if it will show 12 volts on your circuit tester.
