Razor MX 650 wont run

Question edited for clarity.
Question moved from Razor health and beauty category.

It is a known issue, but it may also be that you haven't depleted enough power for it to require a charge?

No/poor connection between power source and motor
Motor failure
Only someone with their hands on the bike can fully diagnose.

I haven't used my razor scooter in years. I just bought a charger and it seem like it is charging but it keep saying it is on low. I twisted the gas thing and it is making a noise like it want to go. But I am not sure I have charge it for 12 hours now. Do I need a battery or is it just taking it time to charge.

I have exactly the same problem and it started right around the time the "gracious" 90-day warranty period expired.....
The battery lights had been on for days, indicating a full charge, but nothing happens when turning the throttle. Battery housing is very cumbersome to open, but I'll try to disconnect the battery next.

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.

If it was working before it sat, then it is almost certainly the battery (these kinds of batteries suffer if sitting and not fully charged). If you had one, or could borrow a voltmeter, you could check the batt. Also, lots of car part places like NAPA can test batteries for you.

Hope that helps

It sounds like the throttle cable needs to be adjusted/connected. Check all the cables/wires going to your throttle.

Although you alternator may be charging, the battery may not be accepting the charge or holding it. Have the battery tested under load, but I think that you are going to find you will need to replace it.

Did you ever find out what the problem was?

Hmm, do you have a voltmeter, check the voltage on the battery with it running, usually 13.5 to 15 volts
If that reads ok, you probably have a short, get a testlight, pull off the negative cable off the battery,clamp one end to the cable and the other to the battery. If it lights up, you have a short, start unplugging stuff until you find the short and the light goes out!
