1999 New Holland lx885 shut off while running, no indicator lights, continuous tone

[zachlindberg]

So i was moving snow and lifted the boom and dumped the bucket and the machine abruptly shut off. Now when the key is in the run position, there is a continuous tone and none of the indicator lights come on. the machine will not turn over. I'm no expert but it sounds like some sort of safety engaging. Any help would be appreciated.

Check your battery connections. Have someone hold a volt meter probes on the battery terminals while you attempt to crank the engine. If the voltage drops below 8v the battery or connections are bad. On the left side of the engine is a fuse and relay panel. Remove the cover and check the 15a fuse at the bottom of the fuse block closest to the engine.

Fuse was good but i replaced it anyways. checked the battery voltage while attempting to turn it over, voltage held steady at 12v.

UPDATE- so we found that the 5a fuse for the instrument cluster was blow. replaced it, and it started right up. when i attempted to operate the boom however, the fuse blown again resulting in the previous issue. We put at 7.5a fuse in and we were able to operate the boom (rather slowly) and limp the machine back into the garage at least. before i shut it off, the instrument cluster showed the code F 0A i'll dig through the forum to find an answer but if anyone has an idea let me know.

First check the seat harness for shorted wires. People like to store items behind the seat which can damage the harness and short the harness out. If the harness checks out then remove the foot panel between your legs to get access to the hydraulic control valve. At the front of the valve are solenoids which lock the foot pedals. Looking in from the front the left solenoid is for the bucket and the center for the lift. The other spool has a switch and not a solenoid. Install a 5a fuse, unplug one of the solenoids an see if the fuse blows. If the fuse blows plug the disconnected solenoid back in and unplug the other solenoid and see if the fuse blows again. If the fuse does not blow then the unplugged solenoid is bad.

The fault code is for the control valve solenoid circuit so the problem is more likely with one of the solenoids on the control valve. What usually happens is one pedal will lock and the other will be free, but if the short in the solenoid is bad enough both pedals will lock or blow the fuse
