Error Code 68 Diagnosis
What This Code Means
2732E Low Voltage Fault (battery / ECU under-voltage)
Possible Causes
- 1On the Sinoboom 2732E, code 68 is a pack / ECU under-voltage trip. Larger platform amperage draw exposes weak cells and loose chassis ground straps faster than compact 13-ft units.
Recommended Solution
Sinoboom 2732E code 68 fix: charge overnight, load-test under lift, inspect battery cables and chassis grounds to the ECU/PCU, then verify charger output. If you actually run a 1330SE, use the 1330SE code 68 guide instead — the fault tables look similar but cable layouts differ by model.

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.
