Hi All,
my throttle broke yesterday and on trying a spare at home it works but you have to go to WOT for it to start and then by working back on the spring the speed slows until stop at what would normally be full speed?! Let go for off and it works back to WOT as it springs closed / open.

So it appears to be operating backwards i think I have tried all the combinations of the three wires (hall throttle on a direct drive hub), and tried reversing the signal and gnd but that stoped it all together. Would this happen with incorrect wiring or is it something else? (New throttle ordered to test)

Any thoughts?

Background: I did try to by-pass the throttle using a magnet direct to the sensor in the broken throttle which latched the throttle on at a level but on removing the magnet it kept running until I held the brake which had to stop the wheel before the e-brake cut off worked or did i trip something (no fuse blew).

The throttle was from a brushed motored bike but that shouldn't matter.

Thanks

You need to flip each of the two magnets inside 180 deg.
Make sure you mark them first in case you drop one, which is very easy to do.
The magnets are inside. Best to remove the throttle from the handlebars before taking apart. For some, they can't come apart on the handlebars.

Thanks for the suggestion, i did open it up but they were stuck fast and would have needed a fair bit of delicate operation to get them out, fortunately the one I ordered off ebay arrived this morning and that one works fine.
so problem solved.;)
