Have new trailer but braking seems rather poor. I have a prodigy P3. Using the manual control I can feel the trailer brakes come on but very little. Setting voltage from 5 to 12 volts makes no difference, brakes feel exactly the same no matter what the setting. Boost settings make no difference.
Shop tested trailer with their vehicle and said everything checks out ok, correct voltage at the brakes etc. Had a different shop check TV's connector and stated all looks good, at least with their plug in tester. It has an LED that gets brighter as the manual lever is increased indicating higher voltage. No idea if their tester puts a load on the controller to simulate brakes.
Any ideas or perhaps my controller is bad?
