i have a CAT skid steer model 232b2. i haven't been able to get the arms to raise up on it. with machine running parking indicator lamp does not come on. when i am pushing the button to release the parking brake, the seat belt indicator light starts flashing. machine will move, but i cannot raise the arms. hydraulics won't engage, but the hydraulic fluid level is good. checked wiring as best as i can, and i see no bare wires. i also have bypassed the seat sensor thinking that would help, with no luck.
