Tag axle controller now beeps....
On my 1999 Thor Residency 3790, I have a Hayes (Kelsey) tag axle controller unit that seemed to work fine until today.
Had some work done in a RV service center and when I left to go home I realized the controller would beep for as
long as I had the brake pedal depressed or push the manual slide button.
It's an annoying tone, like holding down a button on the phone.
Never did it before today and the mechanic was stumped when I took it back.
It is a Hayes/Kelsey Universal Electronic brake Controller #81750.
Tried resetting the gain, resetting the unit by holding down the button until the lights flashed,
made sure the pendulum arm was straight down, and saying all the bad words I know.
I have the original operating manual and it never mentions a tone/beep.
Anybody else had this unit start making a beep/tone??
