Why did my razor ground drifter stop working battery is good

Question edited for typos.

Check for a big red fuse block on the positive battery terminal. The other possibility is a faulty switch if absolutely nothing turns on. Or perhaps the new battery is completely flat due to a fault or discharge. You need a good person with a test meter.

Well most likely, your batteries are weak. When the charger shuts off, the batteries have stopped taking charge, but they're not necessarily at full strength, especially if they've been sitting for a while without being charged. Connect the wires from the power switch together and try again. If it works replace the switch. If not, turn the motor shaft both ways. If it makes clunking noises, it's cooked. Otherwise you probably need batteries. Ive never seen a throttle or controller cause slow operation. And also always keep your tires pumped up.

this unit may take several hours to charge correctly

you need to return to the store you bought it from and explain to them that the battery does not hold the charge.

If the battery is gone(bad), sometimes it will show fully charged (volts are good).. but it has no amperage to "push" the voltage... It takes amperage to make the drifter move... (time for a new battery)... they don't last long...

Hi -
How old is your razor? It's possible that the battery's shot.
One of the problems with rechargable batteries is that they have "memory". If you put them on a charger when, say, they're only at 50%, then over time they'll start thinking that 50% is actually 0%. This is why it's often advised to run your appliance down to nothing (your razor, your laptop, your rechargable flashlight) before putting it on the charger.

Alternatively, your charger might be acting up. Best recommendation would be to take your razor (and charger) to a shop to be tested. This is an expensive razor, and if you like it, it would make more sense (and be cheaper) to get it fixed rather than toss it into the land fill & buy another.

Good luck...

If your batteries are good and are putting out the proper voltage I would say your control mod has failed. Usually all the lights work but all you get is a faint clicking sound everytime you turn the throttle.

replace thumb tab throttle. part is $12.99 from razor. go to razor site to order. i had the same problem after my daughter drove it over a bumpy sidewalk.
