|Can anyone tell me what the voltage should be at plug? I get 12 volts when I move the gain lever. I get 3 volts when I hit the brake pedal. Help!! Wayne|
|DUH; my crystal ball has NO clue what your working on.|
|I'm working on my trailer brak controller on my 06 ford f 350. I have no brakes except when I use the manual gain lever, I completely rewired the trailer. Checked it out over and over again. I get 12 volts at the plug on the brake termanl when I use manual gain. I get 3 volts when I hit the brake peddal.|

A multy meter will not be enough "load" to properly trigger a brake control
Second: The Ford brake control and any good brake control will be "Prportional" braking Meaning that if the truck is not decellerating it will not go over the set "start" voltage. You crank this up a little when you crank the gain, but the brakes don't go 100% untill the truck is working very hard to stop.
You may be able to trick an aftermarket BC by stepping on the brake then tipping it towards the front of the truck. This may (depending on make and how easy it is to fool) increase the supplied voltage.
Either way a make and model of brake control will allow you to down load the operators manual off the net.
