Help with new controller

[Bigkev34]

Good morning all

Could do with some help. Have been given an older ebike 2007 I think with a dead controller and botched wiring.

I have a new one which has the pas and hall sensors on as my bike has them.

I need help with the connections, I have the hall sensor sorted as it was on a multi plug also the 3 motor wires as they were really self explanatory.

From the handle twist throttle I have 3 lights red amber green,there are 4 cables blue red green yellow. The red and blue are the brakes. So guess the green and yellow are power and signal.

They run to the controller housing we're I have another 3 wires coming from a sensor next to the pedals (PAS sensor I guess??) They are black red yellow.

I have added some pictures if anyone could help me. Linked from my Google, with we're the other controller wires go?.

The brakes have blue and red from both brake levers so I joined both sides red to red blue to blue etc then the main wire down the bike frame to the controller housing.


There's we're no batteries with it so I've hooked up 2 12v 7ah ones in searies to give me 24v.

Cheers guys

I gave you all the answers on Endless-sphere. Why are you asking again?

Hi

I contacted the controller manufacturer who said it can be made to work without lcd etc

It can, but you can't adjust any of the settings. Everybody that I know, who tried to run without an LCD gave up on that idea and ordered one. How are you going to change PAS levels without it? What speed limit will you get? How long will it run before going into sleep mode?

If you want to try it without the LCD, join the red and blue wires (battery voltage to controller power wire) and the green and yellow (Tx to Rx data).

To stop it going into sleep mode, you need a speed sensor input. The white wire on the motor white block connector is for the speed signal. if your motor has a speed sensor in it, all well and good. If it doesn't, you need to fit a wheel-speed sensor. For the three-wire ones, you have to take a branch off each of the black and red motor hall wires to power it, for a two-wire one, one wire goes to the white wire and the other goes to either red or black in the motor hall connector - whichever one makes it work. The trouble is, without the LCD, you can't see which one works. You can measure the voltage on the white wire when everything is switched on. If it's 5v, the second wire goes to ground. If it's 0v, the second wire goes to 5v.

One other thing: The controller says 36v and your photo shows two 12v batteries (=24v). A 36v controller will cut off power below 31v.
