HI 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?.

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
 
It's a shame you took all the connectors off. It makes it much harder.

The bunch of cables with a red band around them are for the LCD. The controller won't work properly without one. The LCD costs more than the controller, so it might be an idea to start again with a controller that doesn't need an LCD; however, this controller is very good when you have the LCD. It's probably a sine-wave one and has nice PAS control.

The throttle has 4 wires: One is ground, one is 5v, one is throttle signal and the last is battery voltage for the LEDs. I can guess which is which, but it's best to open it up to check which wire goes to the LEDs.

The brown, yellow and black from the controller are 5v, PAS signal and ground, so if your PAS is red, yellow and black, they connect in that sequence.

If the black red and blue from the controller go together, they're the throttle ground, 5v and signal. what comes out of your throttle isn't clear in the photos. Can you tell us?

That leaves red and blue that must be for the brakes.

The wires that you joined look totally wrong, but it's not clear what is what.
 
Sorry here is the controller picture I thought I had uploaded that to.

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.
