Will a faulty speed pot cause my scooter to not move.

The speed pot is the knob you use to go from turtle to rabbit. You can go to the website of the manufacturer to get a service manual

The speed pot and throttle pots do wear in time. These parts are readily available and are not too difficult to change. A service manual can be downloaded from the mnufacturer's website. It has detailed instructions and part numbers.

Yup you got a code seven failure code, speed pot malfunction . What pots typically do is that they oxidise. This pot is a variable rersistor that opeates between 0 - 30k ohms. When tuning the pot it shoud ram up and down smoothly. To test for this

Disconnect batteries from the scooter. Simply attach the multimeter to the pots terminals, select correct ohms scale and watch the needle. Th needle when turning the pot should move gracefully up to 30k down to zero as the pot dial scooter speed increases. Failure is detected when the needle jumps around, the oxidation causes the pot to connect inteermitently. USE CRC CONTACT Cleaner to get the oxidation out of the pot. The potss are not sealed so there are little holes you can spray into. Use liberal of cleanner.

Hi John.
The problem could be a worn throttle pot ( wig wag ). Next time you are driving the scooter, try moving the ends of the speed lever slowly up and down, instead of in or out as you normally use it. If the throttle pot is worn, moving the lever this way will make the machine speed up or slow down.
Another cause might be a faulty battery lead connector or a faulty motor connector.
Good luck. Neil.

Hi. Most speed problems on scooters, can be the throttle pot ( wig wag ), or the motor brushes.
Also check all battery lead connectors, and the motor lead connectors.
While you are driving along, try moving the speed lever slightly up and down, not in and out as you normally do. If the speed changes, it is probably a faulty pot.
Do you have a high/low switch, or an indoor/outdoor switch that changes the speed? These sometimes cause speed changes. You can fit a new switch or by-pass the switch, and have it on high all the time.
Good luck. Neil.

Hi. A faulty speed control pot ( wig wag ) will cause this problem.
While you are driving along on a smooth surface, move the end of the lever carefully up and down, not in and out as you normally do. Doing this will help to see if there is a problem with the pot, it will cause the speed to vary or change.
Can sometimes be caused by stuck or worn motor brushes.
Good luck. Neil.

Hi. Many scooters will display this fault code if the potentiometer is not exactlly centred when you turn on the key. The pot is not always faulty. Some scooters also have a smaller additional pot to controll the speed. If this pot is faulty it will cause the same fault code. Any other switches such as indoor/ outdoor switches. I have had a few machines fitted with curtis controllers where the fault is in the controller.
Check the wiring and plugs and connectors.
Good luck. Neil.

hi, there could be a number of issues,

First check the speed pot, try moving the throttle lever in the upwards or downwards direction while going forward, if the scooter starts to pick up again then the speed pot is worn and needs replacing.

if the motor has brushes check them, make sure they can move freely, some times they stick and cause intermittant speed problems, check the battery conections and make sure they are tight.

If this helps please vote.

ok, that could be one of three things,

A bad connection with the battery so lift the battery and check contacts,

Check wiring to the speed pot, you will have to remove the top unit that house the speed pot etc (Wign wam)

A faultly speed pot is the other cause, to confirm trying moving the pot up and down, is there a lot of play , try moving the lever slowly, if it jerks about, it needs replacing.
