when you back off the throttle an orange light with a circle and arrow on it comes on, loses power and dumps air by air dryer on chasis. exhaust valve comes on i think, help?
it should... you should have a 3 way switch on dashboard, middle is off, up for foot brake actuation of exhaust brake and down for actuation on release of throttle pedal

trouble is no hand book. cleaned round foot switch to make sure not sticking down. think i tried rocker switch on dash to no avail

think there is a switch on dash/column to control exhaust brake,check in handbook to see how to operate it.
