Have a problem with my brake buddy. when setting up to tow my toad, I press the test button and it should drop one light each time I press it for 5 times then it should turn green, this doesnt happen,this doesnt happen. what is wrong? also I have a problem with the Alert system. I plug it into power receptacle in motorhome , it flashes red once. I went through the test procedure , had someone press the test button on brakebuddy and the receiver does not light up. also pulled the break away but no light on receiver. what is the problem?
