This article explains how to troubleshoot a Kaabo Mantis 10 single-drive model that will not power on. 

Use this article if your scooter:

• Will not turn on
• Shows no display activity
• Only powers on while connected to the charger
• Powers off immediately
• Has no response when pressing the power button

Before You Start

Please prepare the following:

• Your order number
• A photo/video of the issue
• A photo of the display
• A video showing the scooter attempting to power on
• Confirmation whether:
  • the charger light works
  • the scooter powers on while charging
  • the rear motor has resistance when rotated
• Details about whether the issue started after:
  • charging
  • storage
  • transport
  • crash or impact
  • rain or water exposure
  • modification
  • display replacement
  • third-party repair

If there is visible wiring damage, please also prepare clear photos.

Safety Warnings

• Do not continue using the scooter if there is smoke, burning smell, overheating, visible wiring damage, or water exposure.
• Do not work on wiring while the scooter is powered on or connected to the charger.
• Do not allow disconnected motor phase wires to touch each other.
• Do not open sealed battery components.
• Stop and contact support if unsure.

Scooter Will Not Power On

This issue may be caused by:

• Low battery voltage
• Battery faults
• Loose wiring
• Controller faults
• Display faults
• Junction box faults
• Main line wiring faults

Step 1 – Check Whether the Battery Has Charge

If the scooter has not been charged for a long period, the battery may have entered undervoltage protection mode. 

Connect the charger and fully charge the scooter.

If the scooter powers on normally after charging

The issue was likely caused by low battery voltage.

If the scooter still does not power on

Continue to Step 2.

Step 2 – Check Whether the Scooter Powers On While Charging

Connect the charger and attempt to power the scooter on. 

If the scooter powers on only while charging

The battery may require further inspection.

Please contact support with:

• A video showing the scooter powering on while charging
• A video showing the scooter not powering on after unplugging the charger

If the scooter still does not power on

Continue to Step 3.

Step 3 – Check Battery Output Voltage

Disconnect the connector between the battery discharge port and the controller. 

Use a multimeter to measure the battery output voltage.

If the battery output voltage is only a few volts or there is no voltage output

Reconnect the charger and check whether the voltage recovers.

If the voltage recovers after charging

Charge the scooter fully and test the scooter again.

If the voltage does not recover

The battery may require further inspection.

Please contact support with:

• Battery voltage readings
• Photos of the battery connections
• A video showing the issue

If the battery voltage appears normal

Continue to Step 4.

If you are not comfortable using a multimeter

Stop troubleshooting and contact support.

Step 4 – Check the Display Main Line Wiring

Open the battery compartment cover and inspect the XHB8 connector where the display main line connects to the junction box. 

Check for:

• Loose wiring
• Incorrect wiring connections
• Unplugged terminals

If loose or incorrect wiring is found

Reconnect the wiring securely according to the correct wiring layout and test again.

If the wiring appears normal

Continue to Step 5.

Step 5 – Check Controller Voltage Output

Open the battery compartment cover and use a multimeter to measure voltage between:

• The black wire
• The pink wire

on the XHB9 connector where the controller connects to the junction box. 

Normal output voltage should match the battery voltage.

If there is no voltage output

The controller may require further inspection.

Please contact support with:

• Voltage readings if available
• Photos of the connector wiring
• A video showing the issue

If voltage output is present

Continue to Step 6.

If you are not comfortable using a multimeter

Stop troubleshooting and contact support.

Step 6 – Check for Rear Motor Resistance

Manually rotate the rear motor and check for resistance. 

If the rear motor has resistance

Disconnect the motor phase wires from the B controller.

Important Safety Note

Do not allow the three motor phase wires to touch each other. 

Rotate the motor again.

If the resistance disappears after disconnecting the phase wires

The controller may require further inspection.

Please contact support with:

• A video showing the resistance
• Photos of the controller wiring

If the resistance remains

Further motor inspection may be required.

Please contact support with:

• A video showing the issue
• Photos of the motor wiring

If there is no motor resistance

Continue to Step 7.

Step 7 – Check Controller Continuity

This step requires electrical testing equipment and technical experience. 

Disconnect the controller power connection from the battery.

Use a multimeter in continuity mode:

• Black probe on the controller power black wire
• Red probe testing the blue, green, and yellow phase wires individually

If continuity exists between the black wire and any phase wire

The controller may require further inspection.

Please contact support with:

• Continuity test results
• Photos of the controller wiring

If no continuity exists

Continue to Step 8.

If you are not comfortable performing continuity testing

Stop troubleshooting and contact support.

Step 8 – Check the Display Power Output

Use a multimeter in 200V DC mode. 

At the XHB connector between the display main line and the junction box:

• Place the black probe on the black wire terminal
• Place the red probe on the blue wire terminal

Press and hold the display power button during testing.

Normal voltage output should match the battery voltage.

If there is no voltage output

The display may require further inspection.

Please contact support with:

• A video showing the test
• Photos of the display connector
• Voltage readings if available

If voltage output is present

Continue to Step 9.

If you are not comfortable using a multimeter

Stop troubleshooting and contact support.

Step 9 – Junction Box Inspection

If:

• The battery voltage appears normal
• The display main line wiring appears normal
• The controller output voltage appears normal
• The scooter still does not power on

The junction box may require further inspection. 

Please contact support with:

• Photos of all related connectors
• A video showing the issue
• Details of all troubleshooting already completed

Step 10 – Display Main Line Inspection

If all previous checks appear normal but the scooter still does not power on, the display main line may require further inspection. 

Please contact support with:

• Photos of the main line wiring
• A video showing the issue
• Details of all troubleshooting already completed

When To Contact Support

Please contact support if:

• The scooter still does not power on after these checks
• You are unsure how to complete a step
• There is visible wiring damage
• There was water exposure, crash, impact, modification, or third-party repair
• The rear motor has resistance
• The scooter overheats, smokes, or has a burning smell
• Internal electrical inspection may be required
• The scooter is unsafe to use
