Re: little gem mobility scooter brake not working...
The throttle part has slip round, a way to test this is to put hte buggy in reverse slightly and it shoud stop, meaning that how much the throttle has slipped round.
Take the top cover off and there should be a allen screen on the throttle stem, undo and readjust.

hi, they are good readings, the brake resistance is a bit low...however does the brake click when moving the throttle lever to go forward or backwards ?
if the brake is not releasing the scooter will never move...
does the throttle lever feel loose ? you need to convince yourself that the throttle part is working correctly , if you double checked everything including the brake and connectors then we need to look at the controller ..
After a fault has accorded with the scooter and you have reset the fault. Turn off the scooter with the key and count to 10 then switch on again. This will reset the fault in the system. If still have fault, try moving the lever in and out a few times in case the brake micro switch does not make circuit properly.
Hi there sorry to hear your scooters got problems, one or two things could be wrong,
1 make sure the brake lever is engaged properly this will be located at the rear end of the scooter.
2 if the above does not work you could have a problem with the brake itself.
3 does the scooter beep when you turn it on or when you engage the wigwag in the forward motion.
4 if you still cannot get it going give me a call
Things to check: Drive/Free wheeling switch, brake release lever (this activates an internal micro-switch that enable power to the drive system, battery box connectors (condition of contacts - corroded, missing, loose. etc.); main control cable (corrosion. lose or missing pins, etc). If all these are OK, could be controller or drive control potentiometers (speed, forward, backward) on the handle-bar (tiller). Good luck!
That lever is attached to a pot. Pots have this nasty habit of oxidizing. You can either replace it or get some CRC QD Contact Cleaner. Wash it down trying to get as much cleaner into the pot as you can. These pots are normally not sealed find a little hole and spay it there. While your in the control head use the cleaner to clean anything you find in there. Stall having problems contact me.
I would suspect the brake is not releasing correctly and dragging on the motor housing. Try driving the scooter a short distance and feel the motor case at the rear near the brake assembly if it is very warm or hot the the brake is sticking and will have to be replaced. Hope this helps
spares sounds like the throttle pot is not being centered upon release making the scooter move in reverse or forward depending on which way it is off center. try pushing on the thottle lever slowly forward when you stop to see if that stops the creeping. Then you can try to adjust the pot by loosening the lever and retightening it in the forward direction that stops the creeping. You might have to order a new throttle pot assembly to get this working right. Hope this helps
Hi. Are there other faults as well? Maybe you should get another quote from a different technician, or ask him if he has any second hand parts available.
If you use it, and you cant control it, you end up down a bank or under a bus.
What brand and model is it?
Sometimes the brake disc in the brake unit splits and allows the machine roll on. Sometimes the brake lever has had a bump, and just needs to be pushed back into place properly.
Try contacting the authorised service people for this scooter, and get some prices from them. Good luck. Neil.
Hi. This sounds difficult. I have had a few scooters move slowly forward or in reverse, but not both. Normally if the speed pot ( wig wag ) is not exactly in the central position, they can do this.
It is possible for a scooter to have your problem, if the speed lever is binding or rubbing on the housing. Normally the lever is returned to the middle by a spring around the speed pot shaft. If this spring is loose or broken, then this could also cause the problem. Sometimes a small spot of oil or grease will help.
To check the speed lever is in the middle, slowly move the lever for forward untill you hear the brake solenoid release. Now release the lever and slowly pull it for reverse untill you hear the brake solenoid release. Make sure that the speed lever moves the same amount for forward as it does for reverse. If not adjust it with the key off.
If you get the machine to drive properly, then change the controller to see if it is OK.
As for the beeping, a lot of machines will go into an error mode if the speed lever is not in the central position when you turn the key on. This is a safety precausion.
Good luck. Neil.
