New Holland skid steer with no functions

When a New Holland skid steer starts and idles but none of the hydraulics or travel will work, what details help sort an interlock issue from a control or hydraulic problem? Model and any dash code would probably matter.
 
The big split is whether the dash recognizes the machine as enabled. If the lift arms, bucket, travel, and auxiliary hydraulics are all dead together, it leans more toward a seat bar, seat switch, parking brake, fuse, relay, or control lockout than several hydraulic parts failing at once. A dash warning or no change in the parking brake indicator would help point it that way. If it has no codes and only travel or only loader functions are out, that sends it down a different path.
 
Model and serial prefix matter more than people think on these. New Holland changed the dash and interlock setup across different series, and a skid steer versus a CTL can steer the troubleshooting too. Approximate year and hours would help keep somebody from sending you after the wrong fuse or switch.
 
If it cranks, starts, and idles normal, that at least keeps the basic engine side separate from the no-function issue. Watching whether the parking brake light changes as the bar is lowered may narrow it down without digging into hydraulics yet.
 
If every function is dead, watch whether the brake actually releases when the bar and seat are made. If the brake releases but travel, lift, tilt and aux are still all gone, that points more toward the hydraulic enable/control side than a single valve or cylinder.
 
It'd still be smart to look over the main power feeds, grounds, fuses, and relays. A bad connection there can make the electrical side act strange even with the engine running.
