ebike lights not working (but worked for first try)

[borgqueenx]

Hello fellow pedelec owners, i have a problem with my generic 1000w ebike kit from china.
The bike itself works fine but the lights are not working.

I connected the following lights to the controller:
2 of these on the back of the bicylce:

And 1 of these on the front:

And the first try they worked perfectly. Then i retried later and they started flickering and then turning off. Then i tried for a third time and now neither of them works anymore. The LCD still gives light and the bike is as powerful as ever, but the lights will not come on.

What i also find weird is what i measure voltage it gives me 40,8 volt on the imput of the lights, but the battery has a clear 51,8 volts. And as soon as i connect the lights to this 40,8 volt line of the lights it starts going to zero volt, and giving peaks of like ~50 volt that rapidly go down to zero again in miliseconds.

Help would be much appriciated!

EDIT: the 52 volt output works fine on the lights. Immediatly working and staying up, tested 3 times no flickering. But yeah....i can't control those by the LCD They are always on when the battery is connected.

Sounds to me like the Controller has a problem,
Hopefully the fault wont develop into full blown failure for the controller

thank you garry....i ordered a new controller....again....

Oh well done, well in principle anyhow! I remember you asking if you could connect them up, so it's good you have, although a shame something has stopped the correct voltage going through - if the new controller does resolve the issue, please post a how to...
