Lately my low air pressure and emergency brake lights have not been coming on when I first start truck the warning buzzer works fine and shuts off at about 60 psi and buzzer comes on when emergency brake is lifted/pulled on, looked in TM's and replaced the two low air pressure switches on air tanks but pretty sure this only works the buzzer fail safe box, is there another pressure switch for these two lights and if so where is it located, I also found pressure switch on brake bypass switch on dash , I shorted wires together and also active this button and it works the brake bypass light ok! Any ideas?
