When moving at top speed, my scooter hesitates at times until lately when it has slowed down to a crawl, then it will speed back up again. The charge meter is in the green area and I am consistently pressing on the lever. What is the problem?

usual cause of this is the throttle (wig-wag ) controll potentiometer has worn out.to test put the scooter against a wall and get a freind to lift up the rear of the scooter and put 2 large blocks of wood underneath it so the back wheels can rotate
carefully advance the throttle 1/2 way then with wheels turning.keep in same position and gently move the throttle lever up and down .if there is a lot of play and the speed varies drasticaly then pot replacement reqd .you can get a dealer to order the correct one or get one off the internett but when fittinf if thr pot is not set to exact center with multimeter scooter will not move and produce off center error code

If it is actually speed pot related, then removing the speed pot
and spraying down the shaft of the speed pot (from the top)
with electronic contact cleaner, may help to make clean
the pot resistive element and that should fix that. If it's
not a speed pot issue and happened after replacement of
the batteries, assuming they are 35/37 AH AGM batteries,
check the batteries for current delivery at the rated current.
It could be just a battery that is not providing the rated current
to the motor after 50 feet.

I would say that both the batteries are not holding a full charge ....I had one in the past for my mother and if it was not chraged on a regular basis the batteries would die out ....the cheapest and easiest route here is to try new batteries.

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.

sound like motor on the way out

Hi. Does the machine do this more soon after removing the machine off the charger? When a mobility scooter is going down hill, the controller feeds the voltage generated by the motor back into the batteries. When I an testing machines here at the workshop, I have seen cases where 10 to 12 amps is going back into the batteries on a down hill run. If the batteries are fully charged or unable to take much current, the controller slows the scooter right down to limit the higher voltage generated.
It might pay to check the battery leads and connectors as well, and get the batteries tested.
While you are driving along, try moving the speed lever slowly up and down, not in and out as you normally use it. Sometimes a faulty speed pot ( wig wag ) will cause the speed to change.
Good luck. Neil.

Not necessarily modems fault. How old is your PC and have you added anything lately that might slow it down. And have you run a virus scan lately?
Virus and worms can slow you down as well as not enough memory.

Have the batteries tested with a load tester. Usually when it starts to move slow it means the batteries are going.

time so see your local service center

Sounds like you have a bad throttle pot. You`ll need to check the resistance on it or take it to a dealer.
