Hello nice very people,
I have a Quingo Vitesse Mobility Scooter that I am currently 'pimping' to look like a Harley! Before I go any further I will confess to being a complete amateur and not very clued up on the technical stuff especially electronics. So I would so grateful if any replies come back assuming that I know nothing! (keep them idiot proof).

The Scooter is factory fitted with a Wig-Wag controller which has a 'pot' with three wires (I don't know which is which). The Wig wag not only makes it go backwards and forwards but also acts as an accelerator.

I have bought a twist throttle which also has three wires. The Twist Throttle is clearly designed to move a vehicle forward. It has three wires
Blue: signal wire
Black: negative pole
Red: positive pole

when I touch wires to wires so to speak I can make the scooter go backwards and forwards without having to touch the twist! which of course is not ideal!
what I need to know is, is it possible to fit a twist throttle in replacement of the wig-wag, what would I need to do, what else would I need to get and of course most importantly how would I do it.

Please please please keep it as simple as possible because as soon as I start reading some of the technical posts I feel way out of my depth.

Many thanks in advance

Unfortunately as you guessed it won't be a direct wire it up and go type deal. Personally I don't have any suggestions as it's a bit out of my areas of knowledge, but I can say you will at least need a direction switch as well as a circuit of some variety to convert the signals from old to new.

A few things others will ask about since it will determine what course to take...
1) Disconnect the existing pot and measure resistance between the yellow and blue, blue and white, and yellow and white. It should be the same between the blue and white wires as the yellow and white, but just to make sure there isn't some form of offset built in.
2) The same for the twist throttle. Resistance between red and black, red and blue, and blue and black.
3) I'm not sure if it will make a difference or not, but if you can measure voltages between the pot pins and ground with the power on and the pot centered.

I like the idea myself and hope others will be able to guide you along. Good luck and welcome to AAC.

First a dumb question, what are you calling a "wig-wag"? For what I know that means a way to control lights used on police cars or wreckers.

I think your twist grip is actually a hall effect one. Not compatible with a potentiometer type control.

Thank you 'Geek of the Week'. I do have a contingency plan if this is not possible or it's going to be way above my pay grade.
Plan B is to remove the wig-wag, extend the wiring and mount it down by my right foot plate, then fit the footplate across so as I can operated with my foot, pressure on the right to go forward and on the left to go backwards.
I'll let you know how I get on and post more picks when it is finished.
It's my first one, I plan to do others, a Rickshaw would be fun to do.

I have seen references on the internet to the controller that you hand operate on a mobility scooter which have called it a Wig-Wag.

UPDATE
The solution to my problem: I stuck with the original Wig-Wag pot and assembly and created a mount so that I could use it as a foot control, Press down on the front of the peddle it goes forward like an accelerator in a car, press down on the back of the peddle and it reverses. It works a treat. The twist grip throttle controller is fitted to my SKUTA but is just an ornament!

Now on to the next Project........
