Well after over 4 hours reading here I have decided my problem is in the bics system. because my brakes are locked and my lift will not work. If I let it sit for a couple hours when I start the machine, with the bar down and I push the green button I can hear the solenoid click, But just a second and the solenoid releases and all lights go out on the bics box. after that I need to wait a couple hours to repeat the lights on for a few seconds and then off. I would say the bics box would (as my grandmother would say) cost a pretty penny. Any help appreciated Thanks Joe
Search (use the search functions) this forum for “bics” and “park brake“, and or “park pin” there are several posts on how to bypass the park brake and the bics can be bypassed too if needed.
There are sensors on the seat bar, and the older machine (not sure if it includes your) like C series had a sensor on the seat cushion that proved troublesome because of rocks, pop cans gloves, getting under the seat and preventing the seat from compressing under the operators weight and lighting the seat light.
Late this seat switch was replaced as with a push to operated button on the dash. Not sure if the F models came with the seat switch still. Also many older models were updated to the push to operate button and the seat switch removed.
Also check you fuses and wire harness for frays, breaks and poor conections
On the bics box are any of the lights not lit when the operator is seated and the seat bar is down? are any of them flashing a code. Normal is all lights on with operated seated, bar down and push to operated buttton activated
Hopefully you loader does not have the Boss guage option as they are way more of a p.i.t.a. then the standard equipment bics safety system.
