Help! Voilamart 26” front hub looking for repair

[mikeconnect]

You need to measure the voltage on the signal wire (not red, not black) while you operate it. Should be about 1.2v to 3.8v. If it only goes to 2.5v, a magnet has become dislodged.

Thanks vfr and thanks fir all the help

That's great news! Well done for getting to the bottom of it.

With Voilamart controllers, there are two blue wires. If they are connected together, it will limit the throttle to a max of about 10 mph.

See wires No. 4 below:

Thanks I'll check that but I didn't alter any controller wiring and it ran at speed before drop out . Vfr suggests poss magnet dislodged

Thanks and I surprised myself with so much perseverance and a scowling wife in a small living room . As I said not total perfect cos throttle had gone to low power but unless u have some ideas I can live with that and just use it fir standing start . Thanks for sticking with me .

Ps you do deserve medals for putting up with me

This is one of the best parts of the forum, where like minds try and help each other to overcome bike issues. What sometimes make sit tricky is the distant advice and sometimes interpreting what has occurred present or past in attempted repairs.
Some issues are easy to repair whilst others are harder to overcome as the history isn't properly known.

Yeh it's hard at a distance and of course you can't expect immediate assistance from people so it does prolongue the process .
Now I just have throttle to check when I can . But no rush cos in happy enough for now with pedal assist and limited throttle to start me off

It's held in by barbs inside the tube. You have to take it off to access them. There are normally three that have to be lifted simultaneously, which is very close to impossible.

Sorry not clear on that . The throttle is held on by 3 barbs but you have to take it off to access them . But I can't take it off without lifting the barbs ? Please clarify . Thanks

Take it off = remove the throttle from the handlebars.

Take it off = remove the throttle from the handlebars.

Gotcha but I want to open the casing to check magnets and sensor.and it seems like you have to separate the throttle grip from the casing but before you can open casing. So if I'm right i need to know how to remove only the throttle grip
