Good evening, thanks for adding me to the group. I have a 1997 Bobcat 863, SN 54418187. when I start the machine and lower the seat bar, all lights on the BiCS come on (System activated, seat bar, Valve, Traction, power) but often the Solenoid will not release the break. I will move the loader a bit forward/backward, so it's not "leaning" against the brake, might ramp up the rpm and after a while it will release the break. Sometimes it immediately releases the brake when I get the seat bar down. From time to time the brake will kick in while I am driving which will shut down the machine, but it will start up right away. Yesterday, the Solenoid would get in and out so that at the end I didn't know whether the brake was engaged or not. I finally got it released. I disconnected the rpm sensor, when I started the machine, I would get ES-6 "sensor failure". So, I don't think it's the rpm sensor (unfortunately I can't get it disassembled bc some hoses block access. That leaves me with a potentially failing solenoid or a failing seat bar sensor. I don't have a sensor tester. Is there any chance I can test it with a multimeter? Does anyone have some additional thoughts? Thanks a lot in advance!
