Recently replaced the alternator on my 257 and I noticed yesterday when you hit a bump or any kind of sudden jaring actiion it will engauge the parking brake. Doesnt matter if the machine is moving or not. Not sure the alternator has anything to do with it but it wasnt doing this before I swapped it. Has anyone experienced this?
any light blinking? counld be the seat switch, the arm bar switch, several different solenoids. seen the harness under the cab when rolled up rubbing wires against frame. i would start with the seat switch. for testing only, roll cab, while your there check tha harness, install jumper on harness for seat switch. if you dont see bad wires, or not the switch you have to be able to say which light is blinking (park, seatbelt) or if they both are for further troubleshooting.
