Looking for SJ3226 error codes? Read this first

The SJIII 3226 is a relay-based analog machine — there is no fault-code display. It never shows you a number; the factory manual troubleshoots by symptom, and so do we. The only codes on the machine belong to the battery charger (below). Newer motor-controlled units (MC label on the machine) add a controller but still no code readout.

SJIII3226 troubleshooting by symptom

Completely dead: the charger cord still plugged into the wall is the #1 cause — a connected charger interlocks the machine. Then: battery disconnect switch, terminals, battery charge (hydrometer ~1.275 fully charged; a 0.050 spread between cells means a failing battery), fuse F1, breaker CB2, both e-stops, key switch. Past that it’s the relay-and-wire chase — our meter, our job.

Base console works, platform console doesn’t: platform e-stop, key-switch position, or the joystick enable switch — the machine’s core is fine; the fault is in the platform circuit.

No drive or steer while elevated: check the pothole protection bars under the machine — debris or a bent linkage keeps the limit switches open and drive stays cut. By design.

Drives in slow speed only / high-low torque dead: high-speed limit switch or its circuit — the machine believes it’s still elevated.

Won’t lift: manual lowering valve left open, low hydraulic oil, overloaded platform — then the up valve coil. In that order.

Drifts down overnight: lift cylinder gland seal, holding/lowering valve, or the manifold o-ring. Shop job, quoted first.

Charger codes

The 24V Delta-Q charger: solid red = internal fault, codes F-0-0-1 through F-0-0-6 (disconnect AC and battery 30 seconds; if it returns, replace the charger). Flashing amber = external error: E-0-0-1 battery voltage too high, E-0-0-2 too low to start, E-0-0-3 charge time limit (heat, weak AC, or a dying pack), E-0-0-4 won’t trickle to minimum, E-0-0-7 amp-hour limit. Repeat E-codes usually mean batteries, not charger.

Annual inspection for the SJ3226

Skyjack’s decal rule: no recorded inspection in 13 months = don’t use the machine. Annual ANSI/OSHA inspection$225 in-shop, $350 on-site across Chicagoland, same-day certificate when pre-scheduled, renewal reminders included. Frequent inspections (every 3 months/150 hours) can ride on a PM program — ask.

Pricing and turnaround

Repairs are $150/hr plus parts, quoted after same-day diagnosis. If fixing it stops making sense, we’ll say so — and show you a refurbished SJIII3226 with new batteries, tires, charger and a fresh inspection.

SJ3226 service FAQ

What batteries does an SJIII3226 take?
Four 6-volt flooded batteries (24V) — U2200 standard, with US 2200/T-105/AGM approved alternates. Stay inside Skyjack’s approved list and Ah range. We install Crown deep-cycle batteries to this spec — a US-built pack that outlasts the cheap imports.

Why doesn’t my SJ3226 show error codes?
Because it can’t — the SJIII series is analog by design. Symptom troubleshooting (above) is the correct method, or call with what it’s doing.

What oil and how much?
ATF Dexron III or Shell Naturelle HF-E 32; 5.8-gallon tank.

SJIII3226 or Genie GS-2632?
We sell and service both — honest side-by-side here.
