    Hey guys it's been awhile but needing some help. My case 650 k all the sudden won't move and is stranded in the middle of nowhere. Starts up with no fault codes when put in forward of reverse it flashes F or R just like it does when park brakes are set. Have checked brake prox switches, shift solenoids, fuses and connectors and even behind dash and have found nothing. The one thing that I noticed is park brakelight on dash will not come on when p brake is applied. It seems like it thinks park brake is on I'm just not sure where to look next. Any ideas?

    I know nothing about that particular machine, but one thing to try would be remove battery cables for an hour or so and see if a soft code might be causing it? A hard code won't reset, but might get it moving so you can get it somewhere more convenient? Just a thought.

    sorry havent been on since, i went out sunday morning and same problem, i have recently replaced a couple relays thinking that was my problem, tested them and all worked. I have no broke or chewed wires behind dash or anywhere else that i can find and have checked grounds. I kept checking everything and decided to start it up and try again, all the sudden it moves. I still do not have a parking brake light on dash when p brake is engaged.
    I ran for 4 hours on sunday shutting it down twice and it always started up and moved fine after i got it moving, so im really not sure what i did but I'll be on it later this week, see if it acts up again.

    You have a bad connection somewhere in that maze mess of wire and solenoids. Has to be to sudden quit then as sudden after disturbing said stuff started working.

    Thanks DMiller, thats kinda my thoughts too. Finding things like this especially when intermittent can be a real pain.

    I would also check the park brake solenoid and valve ( on the tank behind the batteries) for good function. Power ground magnitizing etc.

    Interesting stuff Hobbytime, but doesn't ship north of the boarder. :(
    Would probably work well on the fuse /relay panels of the case dozers, as they are so prone to corrosion.
