*Came in today and my friend and I both rode **Latest.Bike** Scooter around for about an hour. Was lots of fun and didn't drain the battery much at all!*

[@christianp9128]

Just got a free E175 for my son. I tested the batteries and were bad. I spent around 30 dlls for new batteries. Went trough the hazzle of changing the connectors. Then the scooter will not work. I could hear the click. Took it apart 3 times and assumed the controller was bad since each time it clicked I would get around 0.2 volts going to the motor. Was about to go to bed and order the new controller in the morning. Decided to watch your video and just learned that the 100 series need a kick before starting. That was the issue 😂... Many Manu thanks for the video!!!! My son is happy now.

[@tonykari5124]

I get the same click on my son's Razor 35O & I think they don't need the kick start but I'm gonna check to see if the batteries r bad. Idk what else it could b ??

[@alankeller8204]

2 things - your ion generator is a 1 and a 0, or high and low (on and off). 😅 The second is the infamous 'click' on the E100 with the necessary push off. You saved me on that one! THANK YOU! Now to put it all back together...

You are a great man. You explain so well. My scooter will now be working again.

[@danmassameno6546]

I have news about your "ion drive"! It's not a "I" and an "O", it's a 1 (one) and a 0 (zero). It's from the old days of computers and electrical engineering. 0 is off and 1 is on. Hope that helps. But I do like the Ion Drive bit. ;-)

[@WildPowerSports]

Never knew that! But the ion drive method is a good way to remember it, everyone ive told that to has never forgot!

I have a razor quad with new batteries and fuse. When I turn on power. The throttle lights will light up for a second then disappears? Any thoughts if it’s bad throttle or control module?

[@talonhaskins5333]

I actually had burned the whole wire up going to the on off switch hooking it up wrong and thought I was going to buy another controller at the least because I even hooked it back off and saw the light off so I thought it wasn't working. It ran the whole time and I would have never known.

Can u show how to get rid of the cut off switch mine keeps turning off bat every couple yards

[@brycewantland1804]

For the problem i’m having with the speed kit is that the pedal don’t work when i connect it. Does it matter what model i have? By the way nothing is wrong with my pedal bc i connected it to my stock controller and it worked but not with the speed kit.

[@chrisperrywv]

I have a crazy question. I just picked up an mx650 that someone was about to trash. It has been sitting for 2+ years outside. I have a functioning mx350 in the garage- can I connect the 650 motor to the 350s controller to see if it’s still functioning? The 350 is still 24v stock setup. No modifications at all. I am awaiting new batteries for the 650 and also have no idea if the 650s esc is still functional.

[@dustinirving-carpentier3218]

I have a razor sx 500 last fall was working great now I plug in charger says charged when turn on while plugged in throttle lights up as soon as unplug throttle goes out and does nothing I believe it’s a bad charge controller but not sure also did battery swap still same thing but charge controller is only a year old replaced shortly after bought? Have any idea on what problem is?

[@rhaut4118]

What is the circuit called? Getting it moving before power goes to motor. Would like to look it up to see how it works.

[@etoledofi]

Excellent… I have question I replaced the power button, the reset button and batteries, It looks like is charging, but the power button never turns red. How can I fix that ?? The scooter is running, but the charger don’t get green too. Could you help me with that ?? Ty👍🏽🙏

[@x214214]

So to test the motor on the 24v scooter you just have to connect power and ground??

[@THEBAKER3369]

I have a razor Ground Force electric Go Kart. Battery reads 24 volts wheels turn but not enough power to move a small child. Is it the controller?

Only an electrical kick will make e100 run not a manual turn of motor?

[@quietwon8992]

So wires for the switch, what color are they? That switch went out on mine when I swapped batteries to lithium batteries after a while. Can 36 v controller be shuntmoded ? Is it worth shunting for more power? You said throttle is one speed, I disagree. It's variable on ones I've encountered n worked on. (Rsf650s).

[@robertschilling7711]

I got a different problem.i found a e 150 in the trash and all that was wrong with it was the batteries. I took 2 20 volt lithium drill batteries and it worked fine .faster longer ride time etc. Well just today I recharged the batteries and when I went to turn on the power switch the scooter took off. No kick just straight wide open .I made sure nothing was touching inside the deck and tried it again this time with the scooter sitting on stand to prevent it from climbing the wall but again,the scooter was wide open as soon as I turned o. The switch.im clueless and as I suspected,any video or trouble shooting is geared towards the won't run problems. No matter how I word the Google search it doesn't seem to be a popular problem. So,what did I fry? I'm sure this has to do with the 40 volts that I am using. Any answers would be great.

[@thomasduin2746]

I am aware that you are demonstrating parts of a E bike but I believe a mobility scooter pots work the same. I am trying to troubleshoot a Rascal 305 mobility scooter for a low income gentleman that can not afford to take the scooter into a shop. He said that it just quit working one day. The scooter also has the electric adjustable seat. With the key turned to the right the potentiometer (via the forward/reverse levers) controls the scooter drive motor. With the key turned to the left the potentiometer controls the up/down of the seat height. Both the drive of the scooter and the seat height adjustment are not working. Since the potentiometer controls both this is where I started my troubleshooting. I have 25 volts at the battery, the key switch input and outputs (when on). I jumped from the battery to the drive motor and to the seat adjustment motor and both work. The potentiometer has the following voltage readings: Input: 3.68v Wiper: 2.5v (no matter where the speed dial is set) Ground: 1.3v Should the input be the full 25 volts or is it reduced at the controller box and when received back at the controller jumped back up before going to the motor? The speed pot voltage is: 2.5v at both wires. I am trying to figure out if the forward/reverse pot is bad or if it's the speed control pot or if it is the controller box. Any help would be appreciated.

[@robhdez5048]

Have a Razor Power Core E90. Replaced the 12V battery as it was dead. Still not running. This unit has a ZK1200-DH controller. Diagnostics: (1) Continuity for brake (when in a released position) & push button throttle (when depressed) both check OK (2) Continuity for on/off switch checks good (3) 12.9v measured going into the controller (at controller side connector to the battery) (4) 12.9 V measured between the controller's brown Mid Pin & Yellow wires that connect to the on/off switch (5) Connected 12V battery directly to motor & it sparks up instantly. I suspected the controller, so I replaced it and am getting the same results...will not run even with a good kickstart. What I am not seeing/hearing: When the throttle button (as there is no rotating throttle) is depressed, I do not hear any clicking in the controller (never have since I began troubleshooting it). This is the case for both the original controller and the replacement controller. Quick question: Should I be able to measure the output voltage to the motor at the output connector (blue & brown wires) from the controller (when on & throttle button depressed) or does the controller wait until the kick is sensed before sending 12V to the motor? I am getting ZERO volts from the controller's output voltage to the motor in a static condition & throttle engaged...just don't know if that is normal. Not sure what the next step should be besides throwing it in the garbage 😀 Thanks for any insight on this...

[@robrutherford7]

What should the voltage reading be from the wire that leaves the e100 controller to the motor ? Thanks.

[@WildPowerSports]

We dont say, because this is not useful info in diagnosing the scooter. On the E100, you need to kick off, and should see some voltage on kick-off....coming from you generating it by kicking off! Then the motor kicks in. We never measure this when diagnosing, no need to. If you test the motor and its good and do everything we show, there is no need to confuse yourself here.

[@CoachMcCabe]

I have a 24v Atv. Version 11 if that makes a difference. All of these verified: power from battery, voltage going to and from throttle. Everything is working, BUT I can’t get any voltage to go to motor. It’s not low voltage cut off, breaks are normally in, tried both ways. Took apart the controller and have power going in just no power will go out via the ground if throttle is twisted. Yellow motor wire from controller has voltage too. Only thing I can tel is maybe the little black box in the controller is faulty? I really want to figure out!!! Thanks if you can help!

[@BradWillis]

Question. I have a USA 120v version of the German full-sized scooter Charly. The controller box appears to be toast. Is it possible to repair this box? Do you do this?

Thank you for making this video. It really helped. So I just got a new controller for my son's mx350 bike (his had some bad connectors that got melted) I hooked it up like you showed and had the two extra red wires left but the bike didn't run, so I remembered you say they go to the switch. I unplugged two wires from the switch and plugged those in and it runs. But I'm still having an issue with when I go to charge it, the charger light stays green. I have the same bike for my daughter and use the same charger and the charger goes red when I plug hers in to charge and after charging for a while it will go green to let you know it's charged. I just replaced the batteries yesterday to see if that was the issue, but I'm still having the same problem with the charger. Can you please help? Thank you

[@WildPowerSports]

If the charger never goes to red there is a issue between the charger and the controller. Check all wires, and try a new charger. Did you forget to reconnect the charger port?

[@natashanapolitano3944]

@@WildPowerSports i did, and found that for some reason the new controller was not sending power to the charging port. So I just went and bypassed the controller to the charge port, and went from the charge port straight to the batteries. That did the trick! Everything works and my son is happy and has been riding it since with no issues.

Best way is with a universal controller , throttle, battery, and charger from our web site. Do NOT upgrade the motor, that will slow the unit down. You will add a 4th battery and go to 48V...thats what you want to do.
