Question about Electric Mobility Health & Beauty

Open Question

I have a Heartway Vita mobility scooter using a Rhino 110amp controller. It has two speeds Hihg/Low, I have a need to add a variable pot to control max speed in the Low/High Low setting just like they use in most other mobility scooters. I know it can be done but not sure of pot size and where to wire it in. Can any one help.

SOURCE: I have a pride scooter that will not run at top

hi, first check the speed throttle by moving it in the upwards direction while the speed control is turned fully on, if there is a response to moving the speed pot in up and down direction , you founf the fault, otherwise the speed control is at fault, if thats proves to be okay then its the controller breaking down , check the brushes on the motor.

SOURCE: I have a milan mobility scooter,turn the key & it sounds a low

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.

I have an early version of a ew36 scooter and need to retrofit a speed pot. How do I do this, and any other info or schematics would be great. Thanks

The manufacturer has a variable speed control on the latest version of the ew36. My best suggestion is to contact the manufacturer for the part if it was not available on your version. They may have a retrofit kit with the harness and schematic so you do not have to reinvent the wheel or damage the existing components. You may need a new console cover where the speed control is mounted near the throttle lever. The manufacturer has done the work already and should provide the best guidance. Under driving the digital electronics with a home grown component may produce poor performance and potentially damage the controller sensing circuit. Hope this helps.

Where csn I get throttle pot for a 2003 Sundancer scooter

I am thinking you mean a variable resistor that controls the speed of the machine. ( sometimes called a pot because of the shape) Record any details on the back of the pot and check on line under resistors variable , jaycar, electrical repair shops.

ok so 7 flashes is a speed pot related error, you need to make sure that the speed pot is in the central position , look under the stem and you should see a cross head , now that should be straight not at slight angle, without you touching the throttle lever , if you have a meter disconnect the pot and take a resistance reading, it should show about 2.5K - using the centre tap , if it is a 5K pot fitted , in fact for that controller it should be a 5K pot , please check the terminal connections on the controller, good fitting and clean.
Take leave feedback.

I have a 2002four wheel Legend Mobility scooter.

Hi. A lot of scooters have a seperate switch to select a high or low speed setting.
This switch is sometimes labeled indoor/ outdoor.
I have had a few scooters with a similar fault, and the wires that connect to the high/low switch have broken of the terminals on the rear of the switch.
It could also be a faulty speed control pot.
Check these and good luck. Neil.

Too slow how do I speed it up , a Pihsiang shop rider delux

hi, have you tried another charger as this sometimes can lead to batteries not 100% fully charged , I think the scooter in question is 6mph , check battery leads are a good connection and make sure the speed variable pot on the control panel is working correctly , is the speed pot working correctly (Wig wam) , try moving the lever in a upwards motion while moving forward , does it speed up ? if so it needs replacing.

Ajust speed

Yes, Unfortunately it is a technical solution, the twist grip speed control is a potentiometer (variable resistor) other then limited the amount the twist grip is turned , the only other way to limit the speed is to add a fixed resistor to the "top" end of the "pot", lets say you want a 10% reduction and you have a 1000 ohm pot you would add a 100 resistor to the "top" of the pot, if it doesnt work correctly change the connection to the other endof the pot
