Case SR250. Hydraulics engage, machine goes into stop

[Trevor James]

Having troubles finding a solution. I was doing some dirt work one day. Started backing up in reverse(Adjusting bucket down at the same time) the machine suddenly came to an immediate stop. Threw me back in the seat pretty hard and the Stop light lit up. Bucket didn't move at all. Machine just stopped immediately and I no longer had hydraulic controls. Started it back up, slowly tested all functions for a bit and it was good.

About 8 running hours later I had the bucket tilted down a small amount to back blade and suddenly the bucket kept tilting down all the way lifting the front end making me feel like for sure I was going to roll over backwards. Bucket tilted down as far as it could go and it stopped. Engine still running but the stop light was on on on the control panel and I not longer had hydraulic controls. Tire movements worked just fine. All I got was the stop light and no bucket controls.

Any ideas? Be it here or google I can't pinpoint anything. Did have the error for neutral joystick show up to the point the unit became unusable. Did end up replacing the joysticks. Now after very light use compared to commercial use that error is starting to come back. May be connected? Other than that I'm a loss.

I've worked on a some of those and found that the electrical connections under the cab will get dirty and corrode so unplug them and clean them up and see what happens.
