I spoke with my contact at Tekonsha and he said you want Nothing less than 10 volts at the wheels of trailer. If you are only getting 4 volts from the controller back to the trailer connector then more than likely you have a problem with your wiring. What I would do is inspect both trailer connectors inside and out, looking for corrosion, bent pins, or exposed wire that could cause a short and fix as necessary. I attached an FAQ article on troubleshooting brake controllers for you to check out as well.
