Step 1: Test the MT23 Device Before Installation
Before mounting the screen on your motorcycle, test whether the device can power on normally:
-
Use a Type-C cable and a standard charging adapter to plug the MT23 into a power source (such as a wall outlet).
-
Check if the screen lights up and boots into the Android system.
If the screen turns on, this confirms the unit is working properly. You can move on to check your motorcycle's power supply.

Step 2: Confirm Your Motorcycle Provides Sufficient Voltage
The MT23 requires at least 12V of stable voltage to power on correctly. If your motorcycle provides less than 12V, the screen will not start.
-
Please verify whether your motorcycle battery supplies at least 12V.
-
If you're unsure, use a multimeter to measure the actual output voltage.
Note: Some older or modified motorcycles may not meet this voltage requirement. In that case, consider replacing the battery or using an external power source for testing.
Step 3: Check Wiring Connections
The MT23 comes with a 3-wire harness. Please ensure the following connections are made correctly:
-
GND (Black Wire): Connect to the negative terminal of the battery.
-
B+ (Yellow Wire): Connect to the positive terminal of the battery.
-
ACC (Red Wire): Connect to a point in your motorcycle that outputs 12V only when the ignition is on (this can be tested using a multimeter).
If you are unable to find an ACC wire:
You can alternatively connect the Red ACC wire directly to the Yellow B+ wire, which is the battery’s positive terminal. This will not affect the normal operation of the device.
