Error Code 68 Diagnosis
What This Code Means
1330SE Low Voltage Fault (battery / ECU under-voltage)
Possible Causes
- 1On the compact Sinoboom 1330SE (common indoor rental unit), pack voltage drops below the controller cutoff when one or more cells in the 24V string are weak, interconnect cables are corroded, or the onboard charger never finishes bulk charge between short shifts.
Recommended Solution
Sinoboom 1330SE code 68 fix: charge overnight, then load-test each battery in the string. Clean and torque battery-to-ECU/PCU cables at the chassis. Measure charger output at the plug before replacing the charger or controller. Confirm you are on a 1330SE (not a 2732E / 1932ME sister machine) via the chassis serial plate.

Same code on other scissor lift brands?
Codes 68, 18, 02 and pothole-guard faults mean nearly the same thing on Dingli, Sinoboom, Zoomlion, and LGMG. Read the cross-brand checks before ordering parts.
