Have 6 wires on controller red black yellow white brown green for where the throttle goes broke the throttle that came with kit so ordered one of eBay with same coloured 6 wires. Wired it all up but just battery indicator lights up when I press switch but wheel does not spin. Surely wires should be correct if they all same colour if not any idea where they go. Also my peddle assist sensor I have taken it off the bike does that have anything to do with it does that have to be connected in order for throttle to work? Or is it I've connected wires wrong please help as if not I will have to spend more money on a different controller as my controller with 6 wire throttle is no good an will have to buy one with 3 wires

You don't have to have a pedal sensor for the throttle to work.

The colours are:
Green battery voltage got LEDs on the throttle
Red 5v power for throttle
Black 0v ground
White Throttle signal
Yellow and Brown are the switch wires.

With everything switched on, you must check with a meter between red and black that you have 5v. that tells you that the controller is switched on, then you can check between white and black while you twist the throttle. It should go from 1.2v to 3.8v.

Some of those throttles are wired slightly differently on OEM bikes. It deepens how they deal with the ignition wire, i.e. the wire that powers the controller.

Don't have a meter to check any idea what colours I can try and mix only way to give it a try both controller and throttle have same colour wires so any idea which should be swapped around

The leds are on and switch does switch it on so must be wired correctly? Or is there a chance of a wire being mixed up

Whatever you do, don't try other combinations. If you get it wrong, you can wipe out everything. You shouldn't be messing about with these things without a meter.

Show both sides of your throttle connector so we can see all the wires and their colours. Also show a picture of the controller with all its connectors spread out so that we can see them.

It's a 6 wire throtton there and pas won't work on its own I have to turn the switch on of the throttle in order to get pas working and not many throttles on ebay with 6 wires already tried with wiring up 3 wire throttles but they don't seem to work. Looked on ebay and can't seem to find a cheap controller from UK based seller if there are they are less power or well over 50 quid already spent to much on this bike please any help would be great really need to get this throttle to work

I no the wires look like they not connected properly just hooked them up temporarily to check if throttle works then I can solder once it's working all wires are connected properly just throttle doesn't spin wheel just light up battery gauge

If that green wire touched any of the others, you will have done a lot of damage.

You can't proceed without a meter.

These are the basic tests you should do after connecting everything up and switching on.

1. Measure the voltage at controller's battery connector. Obviously should be battery voltage.
2. Measure the voltage on the 5v rail. You can measure that between any ground (black) and any of the reds going to throttle, PAS or motor halls.
3. Check throttle signal wire. Should give about 1v to 4v when you twist the throttle.
4. Check that the PAS is pulsing. measure the PAS signal wire while turning the pedals slowly. Should pulse 5v on and off every time a magnet passes the sensor.
5. Check the motor hall signal wires (blue green and yellow). They should each pulse with 5v going on and off as you rotate the wheel BACKWARDS.
