Crazy Cart 2.0

[Karriem Drewery]

If it still does not run after pressing the safety button then the next step I would take is to look for loose or disconnected connectors, or for any wires that may have been cut or broken during the move.

These motor wires may need to be checked by hand to make sure that the copper wires under the plastic insulation are not broken. This can be accomplished by bending the wires one at a time up and down the length of the wires and feeling how much bending resistance the individual wires create, then feeling if in one particular area the bending resistance is less than it is in the rest of the wires. If you are handy with electronics and own a multimeter it can also be used to check the resistance of these wires as they are being bent up and down the length of the wires.

Shana Hoercher replied through email: "That diagram that you sent there was no safety switch button anywhere located on the crazy kart the only switch or button that is located on the crazy car is the on off switch. When I press the gas pedal down I can hear the actuator kick on but it does not give any power from that point on. I'm not sure what to do now. Any ideas?"

I would check to make sure that the black ground wire coming from the charger port is plugged into the brass colored terminal on the back of the power switch, if the black wire is plugged into the power switch and the switch does not light up when it is on then the light has burned out inside of the switch. The switch could be replaced with a new one in that case. However if the light inside of the switch is burned out that would have absolutely no effect on whether the Crazy Cart runs or not.

Regarding getting the Crazy Cart running, from the parts that you have replaced and your description of what is happening when the throttle is pressed it sounds most likely that the throttle has failed. It is a common problem with some Crazy Cart versions for the magnet inside of the foot throttle to come loose and prevent the throttle from working. When this happens the controller will click but the cart will not run when the throttle is pressed.

Some people on this forum have been able to glue the magnet back in place to get the throttle working again however I have just read about this and have never done it myself so I can not offer any specific advice on how to get to the magnet or glue it back in place. If your other Crazy Cart has the same foot throttle then you might want to consider hooking it up to the cart that is not running to make sure that the throttle is actually the problem before attempting to repair or replace the throttle.

Since the battery pack and controller are brand new, and the throttle has been tested, and the controller is clicking when the throttle is pressed which indicates that the power switch and fuse are good, the only part left to look at is the motor.

Like the magnet in the throttle coming loose, another common problem with Crazy Carts is that their motor wires will break from the steering wheel being repeatedly turned back and forth while the cart is being driven. Usually only one of the wires will break and the break will be under the plastic wire insulation so it will not be noticeable by looking at the wires. On some newer versions of the Crazy Cart there is a metal spring over part of the motor wires and the wires can break under this spring.

The first thing I would do is turn the power switch on and press on the foot throttle, then slowly turn steering wheel to its full left and then full right position. Sometimes the motor will power on at a certain position that the steering wheel is in, and other times it will not. If the motor powers on during this test then that definitely proves that one of the motor wires is broken. If the motor does not get power when the wheel is turned back and forth that neither proves that the motor's wire is broken or is not broken, and a further inspection of the motor wires are required.

To inspect the motor wires use your hands and bend the individual motor wires back and forth in one inch increments all the way from the motor case to the plastic connector at the end of the wires. The section of the wire that is broken will have less bend resistance than the rest of the wire does. There should be black plastic sheathing over the wires which will need to be removed in order to test the wires. If there is a spring over the wires then it will need to be removed or pushed out of the way so all of the wire between the motor and connector can be tested. Once the bad section of wire has been discovered then it can be spliced back together with an automotive wiring crimp connector and electrical tape can be wrapped around the wire to keep it from bending so much in the future.

This sounds to me like it could be a bent axle or broken rim. The axle is made of steel and could be bent, and the rim is made of aluminum so it is brittle and more prone to breaking than bending. It could also be a problem with the tire or a problem with the way the tire was mounted on the rim. I recommend unplugging the battery pack from the cart so the motor can not run, and then turning the Crazy Cart on its side (preferable on a carpet so it does not get scratched) and inspecting the front wheel by turning it by hand and seeing if it is true or if it has a wobble to it. If the front wheel has a wobble then you should be able to get it replaced under warranty if the cart was purchased new.

Faulty wheel bearings must be a fairly common problem if Razor knew exactly what part you needed as soon as you mentioned the problem. I am interested to know if replacing the front wheel helps. Please let me know how it goes after you finish replacing the front wheel and have someone give it a test drive.

This is actually a second version of the Crazy Cart, which has some design differences from the first model. The two biggest differences are that they moved the battery and motor up front, under the steering wheel, and they replaced forward caster wheels with stabilization posts.

The former change increases legroom for the rider since the battery used to be behind the seat. It also makes the whole thing a bit more aesthetically pleasing since the battery and motor are now hidden under the red hood.

The latter change was made to prevent the vehicle from tipping over when getting on and off or when turning too hard. In either of these cases, as the cart starts to tip, one of the stabilizing posts touches the ground and helps limit the tipping.

Direction is controlled by the steering wheel, obviously, but an arrow on the wheel indicates the direction the cart will move, regardless of how the rest of the cart is oriented. The steering wheel also rotates slightly more than 180 degrees, which not only allows the cart to move in reverse but also greatly increases maneuverability while in motion.
