![]() If the motor spins normally then the motor is not your issue. To test a motor simply apply 12 volts from a battery directly to the motor while the motor is unplugged from the car. If you hear both motors spinning but one of the gears aren't turning please move to the next section. To be clear, this section is for the motor not making any sound. Pro Tip: 95% of customers with Bravo Grave Diggers report solving fuse blowing issues by getting a new shifter from Bravo. Without that you will blow fuses, gears, motors, and your wallet.Ĩ. The spinning wheel is the cars only clutch. If you're running rubber tires take them off. Never use batteries higher then 12amps.ħ. If you replace with our upgrade batteries they will come with 40 amp fuses. ![]() As they age they handle less and less amperage. If you're using stock Power Wheels brand batteries be aware that they have a 30 amp breaker built in. This problem can also shred final gears, third gears, and gearbox housings.Ħ. Check your rear axle for even the slightest bend. If you tightened the motors using a power drill take them back out, put threadlock on the screws, and hand tighten the motors.ĥ. If you spliced wires for any reason take the splice apart the splice and make sure it is done right. It's a good idea to have some spares if you're increasing the voltage.ģ. Switches are cheaper then an ohm meter so if you don't have a meter just get the switches. A switch can look good on the outside but be bad on the inside. Test all of the switches with an ohm meter for resistance. If the copper wire looks black you'll need to replace that section of wire harness.Ģ. If there's green or black then clean or replace the connectors and replace the switch. Inspect the bottom of the foot plunger switch. Here's some things to try (in no particular order):ġ. The only proper way to do this is with a Soft-Start Lithium Module. Adding a voltage regulator will not change the discharge rate. It's like the analogy we gave above but the residents all think they're Mario Andretti. Lithium power tool batteries have a much higher discharge amperage rating and can cause fuses to blow and other problems. Ride-ons are designed for SLA style batteries. Fortunately shifter switches and foot pedal switches are cheap and easy to replace so don't sweat it. As the switches age their ability to handle increased loads lessens. In good condition a Power Wheel's wiring can easily handle 24 volts of power and 775 size motors. It can also occur in any connector you've added into the system. This most commonly occurs in places electricity has to make a "turn" such as shifter and foot pedal switches. Like having a section of road that narrows on a busy highway. If at any point along your highway (wiring) there is an inefficient area the amperage overflows and the fuse/breaker pops as a safety. When you use faster motors (build a bigger arena) or increase the voltage (build more houses) you increase the traffic flow (amp flow). Your motors are a sports stadium and your battery is the residents. Voltage is the number of cars driving and amperage is the speed they move. Think of volts and amps as being a highway system. We recommend using a 40 amp fuse or a self-resetting breaker as soon as you upgrade either the battery or motors. Increasing the voltage or installing faster motors also increases the amp flow. The fuse/breaker in your car is designed to work with the maximum allowable amperage flow for stock motors and batteries. It's easy to think the new parts must be the faulty but that's almost never the case. Sometimes when you upgrade your power wheels it starts blowing fuses or popping the breaker. Trouble Shooting Your Ride-on Car Car blows fuses or pops breakers:
