What else than parking brake does this warn for?
Do you have a S/N for this machine? To the best of my knowledge it only indicates the parking brake is on but if I could check the wiring diagram I might be able to see something else.
Based on the 9WM prefix posted on an earlier thread this is what the O&M Manual says ........... It's a pretty simple parking brake, manually applied with a cable. I would question if the switch that applies the "Brake on" light is defective or alternatively not adjusted correctly. If that's not the case then maybe the neutral signal from the transmission control direction has gone AWOL. The parking brake is on the rear side of the front axle housing. The braking force is applied with a lever and a cable assembly. The parking brake is manually actuated. This is done by pulling upward on a lever assembly that is operated by hand.
Okei, thought maybe it had more to it. Some kind of pressure og warn brakes alarm. Thanks Nige
