i put the blue to black pin on the multimeter and the brown on the black pin it shows 053

i hooked the blue to the red and brown to black stil nothing on the throttle LED

Sorry...I am out of ideas... I suppose it's possible the controller was damaged by putting reverse polarity on it.

Maybe someone else has ideas.

I'm new to this too... but I would try a different wire connector or figure out a way to make sure that isn't the problem. Are you sure the wires are hooked up correctly to the wire connector?

yes im thinking the controller is damaged probably.

but if i connected it wrong does the motor in the wheel take damage too? need to know which parts i need to replace:S

As for the motor, I doubt any damage there. However, there are folks out there who know a lot more than me about this stuff.

i actually think the controller was defective from the begin.

i sent email to the store asking for a replacement

I'd still check the connection. It's hard to tell from the photo exactly what connector you're using, but in looking up the brand (Wago) it doesn't appear that wires of different polarities are supposed to go in the same block. I could be 100% wrong here, again can't tell exactly what's going on from the picture and I'm new at this too.

I also am not familiar with those Wago connectors, but just assumed they were OK. I would also try getting rid of those and just use wire nuts at least for the testing phase.

I got it to work now! it was the stupid wago connector its not connecting the wires properly. I end up trying one last time twisting the wires togheter and its working fine now.

I want to thank dilkes for the amazing help. Without you this would not work! i would end up throwing the whole kit away seriously.

I will come back if i need more help or have questions.

Again thank you so much everyone but special thanks to dilkes

I am pleased you got it working. Truth is, it was buffalo_cody who pointed out a possible issue with the way you were using those connectors.

Your investment in a multi-meter is worthwhile. I personally would never hook anything up without checking polarity/voltage using the meter first, no matter what colour wire was used by the manufacturer.

Happy riding! You're hooked now!

Make no mistake about it…there is no great deal of expertise in building a drive system for an electric bike. It is not rocket science….it is not even as hard as tuning a car science. DIY e-bikes have an array of wires that can quickly and often times turn into a rats-nest if the builder is not thoughtful. Wires are a messy problem. Where as the rest of the technology industry is going wireless, it seems that e-bikes have just as many wires as ever.

Yeah so much time wasted for a small problem. In sweden the brown is allways plus and the blue is minus. So i thought there is no way that its suppose to be the other way around. Im guessing the battery is probably connected wrong.

Anyway i tested the bike today, holy sh**t its fast as f**k. I was speeding past cars and they were all looking at me wondering how

I put the controller on the rear rack, then i carried the battery in a backpack. This is probably the best solution for me because the battery does not fit the frame nor the rear rack.

Sweet!
