Is there anyone here that fixes these things as I need a throttle pot for my father in laws scooter, not sure what the scooter make is but the pot is a 5k ohm part number CM46371.
I need to get this sorted as he is house bound without it, I have found the part im looking for but it is far too expensive from this shop  - http://www.mobilityexperts.co.uk/products/mobility-scooter-potentiometer-slash-throttle-pot

Any help would be very appreciated Smile

Hi, you could try either RS components or rapid electronics for this part. There technical helplines are usually very helpful also.
 
Good luck

I can't believe they are charging £135 for that!!!!!!   I would have said £13.50 was too expensive.

£5 tops.

Any idea as to what wattage you need? As above they will have what you need.

Scooter one here http://www.nithsdale-wheelchairs.com/page/engagers_wig_wag_assy  bottom of page. 


Edit@

found one on ebay with the price - £10  http://cgi.ebay.co.uk/MOBILITY-SCOOTER-VARIABLE-SPEED-CONTROL-/140401100886?cmd=ViewItem&pt=UK_Health_Beauty_Mobility_Disability_Medical_ET&hash=item20b08ec856

This may help also:


It is imperative that the ‘pot’ is set in it’s neutral position for it to work.
Failure to do this will result in the bleep error as mentioned
previously. Generally this can be done by aligning the slot in the
shaft with the middle terminal (2) and switching the scooter on, if
there is a bleep error switch the scooter off and re-align the pot and
switch on again until the bleep error disappears.
A multimeter may be required to ‘fine tune’ the pot to get the neutral
position. Use wire 2 as the common and test either side terminal, the
resistance should measure between 2.5 and 2.6kΩ each side. Use a
flat bladed screwdriver in the slot to adjust the pot. When neutral is
achieved, tighten the grub screws which hold the wig-wag lever onto
the shaft of the pot.
Reversing the polarity
To reverse the polarity (reverse the wig-wag function) simply desolder
the two outer wires (1 & 3) and swap their position and resolder.

Sounds like Maplin may be of use there too.....

Is that off the forward and reverse lever (wig wag) or is it off the seperate speed limiter? I have limited knowledge of these things, but I recently took one apart to build my boy an electric car from the bits. I am told that the "wig wag" throttle pots are unique to mobility scooters because they work over a limited range of movement in forward and reverese about the centre point. That may be why you can't find one easily. 

the potentiometer has a 270 degree travel, but only about 60 degrees is used for wigwag control, from full forward to full reverse.
