We will also disconnect the wires at the connections and leave the female end of the battery then we will try to connect a wire to one side of the plug, and run the other wire to a fuse protector. Inside, you’ll see the plug and wires connected to connectors like those on a regular battery. You will maybe need prepare the original Power Wheels battery to remove the top or the cover if it has. This will result into a total of 24V powered batteries that serve the engine but will not change the amperage. The idea is simple, we have a new 12V battery that we will connect to the existant circuit.
The stock battery will only have a 10~ minute run time with the new motors. and these beastly Traxxas motors exacerbate that. The stock 7.2Ah batteries have a pathetic run time with stock motors. Replace the plastic cover on the wire channel.īatteries: Consider upgrading your batteries while you're performing this mod. Make sure to note the line (wire from battery) and load (wires to motors/accessories) and attach them to the correct side of the breaker. Remove the strip and find the breaker (small black rectangle in the picture). There is a plastic strip that covers the wiring channel. It is located on the underside of the vehicle. You will also need to replace the auto-resetting circuit breaker. Do not exceed 40a and do not eliminate the fuse entirely. Unscrew the factory fuse holder, cut the wires and splice in a 40a cartridge fuse. These motors draw a lot more current at startup than the stock motors. If the motors or wires are too hot to touch, they are being over-stressed and you need to stop usage, allow them to cool and then change your riding conditions (less weight + flatter surfaces = easier on motors). After this modification, I only allow 1 child at a time to ride the vehicle to keep the stress on the electrical system to a minimum. Your application is unique and you need to monitor this for your childrens' safety. Warm weather will also further overheating issues. Grassy, hilly yards with heavy children will cause more strain on the electrical system than hard, flat surfaces with lighter children. IMPORTANT: This modification will require that you periodically check the vehicles wiring and motors' temperature during use to ensure safety. Then reassemble the rear axle, gearboxes and wheels, which is just the reverse of step 1. If it won't turn, you might need to adjust the depth of the pinion on the shaft to make sure it lines up with the gear inside the box. Spin the wheel adapter on the gearbox to make sure the motor turns freely and there is no grinding.

Now install the new motor into the gearbox with the two screws used to hold the stock motors on. I like to use blue loctite threadlocker to prevent them from coming loose during driving. The pinions just slide onto the shaft of the new motor and are tightened with a set screw. (You can likely use a 14t or 15t pinion to increase top speed further, but I've yet to test that).
The new motors have dual plugs for r/c application, so cap the second wire with shrink wrap or another bullet connect that isn't connected to anything.Ĭheck your new pinions vs the stock pinions to ensure they are exactly the same pitch and tooth count. You'll need to cut the harnesses off the stock motors, then crimp a female bullet connector onto the cut end. The new motors come with male bullet connectors.
