For a project, we are using razor parts and we bought the electrical parts for the razor e300 and tried to make a circuit. However, our circuit showed no signs of working and nothing has happened. We have already tried many things, like charging it for 48 hours straight and checking loose connections. That made us think that we might have ordered a wrong part. We bought parts from a version 17 Razor e300.and we were using the wiring diagram listed here. One thing we noticed from the troubleshooting diagram was that the throttles lights were supposed to light up, but our throttle didn't even have lights. Is a Razor e300 throttle supposed to have lights on it?. We also noticed that our e-kit's color wires didn't perfectly match up with the wiring diagram. They fit the opposing wires, but the horizontal colors weren't in the right order.
If you can not get the motor to spin here are some things to try:
A good 24 Volt battery pack will have around 27-28 Volts in it after being fully charged.
Please let me know how it goes.
If the power switch light is on when the charger is plugged in, and turns off when the charger is unplugged that is an indication of an old or faulty battery pack or a faulty wiring harness or circuit breaker. If the controller makes a clicking sound when the throttle is twisted that is almost always because of an old or faulty battery pack.
The motor should run when connected directly to a battery pack. If it does not then either the battery pack or motor are not working.
If the controller was clicking when the battery charger was unplugged from the scooter, then power from the battery pack was reaching the controller which indicates that the circuit breaker and wiring harness are good, and the battery pack is bad. If the controller was clicking when the battery charger was plugged into the scooter and the wall, then the problem could be the battery pack, circuit breaker, or wiring harness.
Circuit breakers are self contained and nothing goes into them or can be taken out of them. The Razor E300 circuit breaker has a button that will stick out just a little from its neck when it is not tripped, and will stick out significantly more from its neck when it has been tripped. If the circuit breaker is worn out the button will not stay when pushed in, and will always be in the tripped position.
Please let me know how it goes.
Sometimes used electric scooters are modified with different parts so if the scooter's circuit breaker does not look like the one in the photo above then someone may have installed a non OEM circuit breaker before you got the scooter.
If the fuse is missing from a fuse holder then power from the battery pack will not reach the speed controller. If the Razor E300 scooter needs a fuse then 30 Amp is the correct fuse rating.
I looked at the image you attached and that is the battery connector that plugs into the controller. The circuit breaker should be attached to the battery pack wires as shown in this wiring diagram.
Do you know of any place where we can buy the circuit breaker? By itself would be ideal.
I do not know of any local stores that would carry that circuit breaker however we sell them in our online store for $5.95. They are item # RAZ-RESET and are located on this page: http://www.electricscooterparts.com/razore300.html
