you could have several different things wrong to cause this. Batteries not charged or can't charge due to bad one, bad motor, bad control module, or bad connection in wiring in one or more places. My grandson's mx650 worked fine for a dozen or so charge cycles but then started with intermediate starting problems. The power light was red and the full light would be green but switch to low amber light and back and forth on its own with no motor response when was on low amber light. He had been running it in wet conditions a couple of times and am sure that was what caused the problem which after taking the battery panels off and examining closely found what was wrong. This problem caused the intermediate starting and stopping and also would not let batteries charge right. I moved wiring while looking at the green light and amber light and found when touching the fuses connections is when lights would change. looked at all 3 30 amp fuses and 2 of them was burnt and pitted. You could see the ark in low light at the fuse when you operated the throttle, that turned out to be a good test to see what was wrong and what caused the fuses to become pitted. I sanded the fuses and clean since they were not blown and used dielectric grease in the connection and that seems to have fixed the problem. I also used the grease in some of the other connections for good luck. The bike charges now like is supposed to and the throttle lights are ok now, no more going from green to amber when wanting power. I would say the running in wet conditions is what started the problem and washing off the bike with a hose would do the same thing.

First try and see if those battery were dead and try a different kind. If that doesn't work notify the person you bought it from or the store about it and ask for a trade in.

I think you are talking about an electric motor on your bike . If the motor is New you may have a bad throttle switch . You can use an ohm meter to check the throttle switch . Connect the two leads of the ohm meter to the wires of the throttle switch ( dissconected) . As you turn the throttle the ohm reading should coraspond to how much you turn it .

Razor MX500 Dirt... | Answered on Nov 09, 2018


I had this same issue with the Razor E100. I couldn't even remove the plastic cap it was so recessed. Here's what worked. The value comes from the factory very recessed in. It's so far in it's hard to remove the cap with your fingers. You'll need to get the value loosened up and pushed out a bit. You will do this from the other side of front wheel using the hole. The value can be manipulated slowly to stick out about an inch from the plastic wheel. It takes some time and patience. First, you’ll need to turn the scooter over and rest it on the handle bars and back of the deck. Put a towel or flatten box under it if working on a rough surface to protect the scooter. Then used the supplied Allen wrench or similar object by putting the long end of the wrench into thru the opening hole on the other side of the wheel. Wedge the edge/end of the wrench against the value from the other side of the wheel and push hard to loosen up the value. This takes some time. Do this on both sides of the value and also against the center of the value. It took me about 5 mins of careful pushing. Eventually you will be about the get the value to almost a right angle from the wheel and sticking out about and inch. Then remove the plastic cap. This will give you room to attach a bike pump. I actually had to push the value back in a bit once finished so the wheel could turn freely. It will work, just be patient and forceful. Take your time.
