Open the alarm report of the OTHER_CHARGER_FAULT alarm on Fleetwrangler.
2 question
Look at the alarm window in ZERP to find the alarm code. Is the alarm code
268458112? 3 action
This is a persistent DeltaQ charger processor initialization error. Create a charger work order using the Charger Work Order template with the notes "this charger should be RMA'd to DeltaQ".
4 action
Some faults are intermittent. Restart the charger service to see if it resolves the issue. For steps, see Restart Dock Charger Service.
5 question
Did the alarm clear?
6 action
If the Zip can be charged normally and no new alarms show up, the Dock may be put back into service.
7 question
Determine if this is a short circuit fault. Pull up the Dock and Zip asset IDs on Baraza and use the template Zip ↔︎ Dock Charging Health. Is
charger_status.short_circuit_status set to SHORT_CIRCUIT_DETECTED? 8 question
There are potentially two types of short circuit faults: 1. Charger internal short circuit; 2. External short circuit fault. Does
actual_current and lz_zip_charge_voltage spike right as we detect a short circuit? Typically you will see a current spike 5-10A in the actual_current. 9 action
External short circuit fault means there may be a short on the charging interface between the Zip and Dock. This is more likely on the Zip side due to distro board failure. Create a work order to check for shorts on the docking fin or the Zip's distro connections.
Context: During docking, the Dock applies voltage before the Zip's charge switch turns on. This lets the Dock safely check for short circuits before current flows into the Zip. If all looks good, the Zip then enables charging. In the case of a short circuit, the Dock applies voltage → current spikes to 5–10 A → Dock stops charging and raises an alarm. Normally, current should stay near zero until the Zip enables its charge switch

Charger internal short circuit fault can be falsely triggered due to the high sensitivity of the short circuit detection firmware. In most cases, there is no meaningful current in

Read
charger_fault_info.error_code / dock.charger_status.alarms.alarm_report and convert the reported decimal value to hex. Which error code is reported? 13 action
Follow Power Cycle / Reset Tripped Dock Breaker to turn off the circuit breaker to the Dock for 10 seconds, then turn it back on.
14 question
Did the issue persist after the breaker reset?
15 action
Create a work order to swap the charger. Include a link to the above Baraza plot.
16 action
If the Zip can be charged normally and no new alarms show up, the Dock may be put back into service.
17 action <=2026.15
The initial charger service restart did not clear the fault. Follow Restart Dock Charger Service for each retry: wait 5 minutes and restart the charger service again. If still unsuccessful, wait 30 minutes and restart the charger service again. If still unsuccessful, wait 3 hours and restart the charger service again.
After those retries, follow Power Cycle / Reset Tripped Dock Breaker to try a hard reset of the Dock at the breaker. If that does not work, create a work order to replace the charger.

Repeated charge-start failures first set
The default action for an active slow-recovery alarm is to leave the Aircraft docked and allow recovery to continue. If the asset needs to be restored before the 24-hour recovery window expires, use SLOW_CHARGE_RECOVERY_ACTIVE to troubleshoot the underlying Dock or Aircraft charging issue.
SLOW_CHARGE_RECOVERY_ACTIVE. The Aircraft retries charging over a 24-hour recovery window and the Dock will try to restart its charger service. If the recovery window expires without a successful charge-start attempt, MAX_RETRY_ATTEMPTS_FAILED sets.The default action for an active slow-recovery alarm is to leave the Aircraft docked and allow recovery to continue. If the asset needs to be restored before the 24-hour recovery window expires, use SLOW_CHARGE_RECOVERY_ACTIVE to troubleshoot the underlying Dock or Aircraft charging issue.
