How to test a brake controller
My friend has a Prodigy brake controller. How can I test it to make sure it is working without a trailer. Can I connect a VOM to the ground and brake connection on the 7 pin connection and then activate the Prodigy controller and see if there is voltage reading?
I believe that if I connect at the ground and brake line connections and then activate the controller I should get a voltage reading and if I squeeze the controller levers it should increase voltage. Is this correct?
