277c serial number JWF00311. Installed a new battery now parking brake won't release. Hydraulics all operate. Seat, armrest and door sensors all work. Yellow caution light flashes along with a solid red parking brake indicator. If you move the left joystick around with the key off then start it the caution light will not come on until after you press the parking brake release button. This machine is not equipped with the pattern selector switch. I cannot get any codes to come up in the information center. Is there a reset procedure after changing the battery or any ideas what the problem might be? I have read there is a service bulletin on the left joystick but have not been able to find it to see the covered serial numbers. Any help would be greatly appreciated.
