The Skyjack SJIII 3219 is a 19-foot DC electric scissor lift with a 24V 225Ah battery system. Skyjack's design philosophy is simplicity—fewer electronic components means fewer failure points. The SJIII series has earned a reputation for reliability in rental fleets.

Known issue: the charger interlock system. The 3219 won't operate while plugged in—a safety feature that sometimes malfunctions. Symptoms include function lockouts even when unplugged, or the charger refusing to start. The interlock relay and associated wiring are the usual culprits.

We stock replacement interlock relays, 24V chargers, and wiring harnesses for the SJIII 3219. Our chargers are tested for Skyjack interlock compatibility—some generic chargers trip the safety system. Don't guess. Get the right parts the first time.
