Begin by securing the battery terminals and confirming correct polarity before connecting the main power switch. Use insulated connectors rated for at least 15 amps to prevent overheating and ensure stable current flow for the drive motors.
Link the dual motors to the gearbox using color-coded cables matching the forward and reverse leads. Test each motor independently to verify rotation direction and adjust connections if necessary to avoid strain on the transmission.
Install the steering potentiometer and control board carefully to maintain smooth handling and responsive input. Route signal and power lines away from moving parts, securing them with cable ties to prevent abrasion or accidental disconnection during operation.

Connect the power supply first, verifying that the positive and negative leads are correctly aligned. Use terminals with heat-shrink insulation to reduce the risk of short circuits and maintain stable voltage for the motors.
Attach the dual propulsion units to the transmission shafts using the supplied mounting brackets. Ensure the gear alignment is precise to prevent premature wear or binding during operation.
Route the main power cable along the chassis edges, securing it with zip ties at intervals of 5–7 cm. Avoid crossing moving parts or sharp edges that could damage the insulation.
Link the throttle and speed control module to the drive motors using the color-coded connectors. Verify continuity with a multimeter to confirm that forward and reverse directions respond correctly before final assembly.
Install the steering feedback sensor next, aligning it with the front axle pivot point. Connect its signal cable directly to the control board and secure the wire to prevent interference from the motor vibrations.
Check all fuses and inline protection devices to ensure they match the current rating of each component. Replace any that show signs of corrosion or mechanical damage.
Test the entire system in short bursts before full operation. Observe the battery voltage drop under load and ensure motors reach full rotation without overheating or unusual noise.
Finally, label each connection on the board with durable tags or colored markers. This simplifies troubleshooting and future maintenance, reducing downtime and potential errors.
Connecting the 12v Battery and Main Power Switch
Attach the battery terminals with firm, corrosion-free connectors. Ensure the positive lead connects to the switch input and the negative lead is grounded to the chassis. Use insulated ring terminals and tighten bolts to 0.5–0.7 Nm to prevent loose contact.
Install the main power switch on a stable panel within easy reach. Position it away from moving parts and secure with mounting screws. Route the input and output cables along the frame, using cable clips to maintain separation from vibration sources.
- Check polarity with a multimeter before powering up.
- Include an inline fuse rated for 15–20 amps to protect the motors and electronics.
- Ensure all connections are free of paint or debris for optimal conductivity.
