Hydraulic fluid breaks down from heat, moisture, and dirt. Just as serpentine belt noise signals engine trouble, milky or burnt fluid means your hydraulics are failing. Learn how to check, store, and replace your oil.
5.9 Cummins oil capacity guide. A dipstick can be misleading on an older truck. Years of repairs mean the dipstick and tube may not be the original pair. A mismatched set can make a low fill look fine or a correct fill look overfull. Before you trust the stick, check a few things. Is the truck on level ground? Did you wait long enough after shutdown? Is the tube bent or damaged? Is the dipstick the right one for the tube? Has the pan been replaced? Is the filter fully saturated? Those checks matter more than the chart on a high-mileage truck.
Before grabbing your tools, make sure your Bobcat is powered off. You need to disconnect the battery and remove the key to prevent any electrical shock or accidental starting. Then, refer to your owner’s manual to locate the fuse box. Typically, the fuse box is located under the dashboard, near the driver’s seat, or in the engine compartment. Some Bobcat models may have multiple fuse boxes.
Skyjack fault codes list. A blinking LED on a scissor lift stops work quickly. Most of the time, the machine is telling you what is wrong. Every flash code uses the same X/Y pattern. One burst of quick flashes, a short pause, then a second burst. A longer pause ends the sequence. So 1/2 means one flash, then two. Before you match it to a chart, confirm which module the LED belongs to. The GP102 runs lift and drive on earlier electric scissors. The GP106 handles outriggers on rough-terrain models. The GP108 runs lift and drive on newer ANSI machines. The same flash pattern means different things on different modules.

You can test an alternator off the car with a multimeter, jumper leads, and a fully charged battery — but only if you power the field circuit and spin the pulley fast enough to excite the unit, because an unexcited alternator will look dead no matter how healthy it is. That’s the premise running through this guide, which works from the vehicle to the bench in a deliberate order. First come the on-machine checks: battery voltage with the engine off, charging voltage at idle and raised RPM, and voltage under electrical load, since low readings there can just as easily trace back to a discharged battery or corroded connection as to the alternator itself. If the fault follows the unit to the bench, the guide pauses at one of the most skipped steps in charging diagnosis — the pulley. The one-way clutch common on modern alternators should lock in the drive direction, freewheel the other way, and turn without grit or wobble; a faulty one mimics a dead unit at a fraction of the repair cost. The bench tests themselves run in sequence: continuity and resistance across the rotor and slip rings, diode checks in both directions to catch a failed rectifier, and a loaded output test with the shaft at speed, watching for voltage that rises above battery level and holds steady. Rounding it out is a symptom-to-fault breakdown that sorts alternator, pulley clutch, regulator, and wiring failures apart, plus the common bench mistakes — slow spinning, missing field power, weak batteries — that send good parts to the scrap heap, and a practical ten-step order that gets you from warning light to a confident diagnosis without replacing anything that isn’t actually broken.

Why is a new oil seal still leaking? Most of the time it is not the seal’s fault. Check when the leak starts. If fluid shows up right after assembly, look at the fit. A nicked lip. A rolled lip. The wrong size. A seal installed backward. Dirt in the bore. If it stays dry at rest and leaks once the shaft turns, look at movement instead. Shaft runout. Worn bearings. Misalignment. Dry startup. A new seal can hold fluid while sitting still, then lose contact once the shaft moves off center. Pull the seal and look at the lip. A cut edge or a rolled lip will leak right away.
