Hello from South Yorkshire.

[mac41]

To introduce myself, I am now retired and in need of exercise and interest. Having spent some time as a guest going through the information on this site. I ordered a set of equipment from Outrider, this arrived in Nov 13.

This was to convert a Brompton M3L. My problem, I thought I had gained enough knowledge to complete the conversion, it is now evident I need some direction.

The mechanics of the conversion is complete but the application of the control unit has me confused. Ie the kit came with a control unit with multiple outlets that did not match the supplied wiring diagram. Some connections are obvious, but the throttle lead colours don't match.
My main concern is to check that the motor functions, it came with the cable exit point slightly damaged, in that the 3 wires were crushed, but seemed to be okay when examined. As I can't get any motor movement no matter how I connect the control unit. Any advise on the motor would be much appreciated.
Thank you

Thhrottle connection usually has three wires. Normally coloured red/black/something else. Red is 5v, black is 0v, the othe is the signal.

Perhaps you can post some pictures, then we will be able to help you with more precise answers.

Thank you, will try to attach image of the controller, marked up with labels of use.

Perhaps the throttle connector has a signal for battery level. How many wires on the throttle?
Have you got a meter to check out what voltage on each pin?

You have to pedal beforen the throttle works IIRC.

The white wire's for programming the controller.

There are 4 wires from this connection.Green,Black White Red.
Meter reads Green to black 40.1v, Green to white 36.8v, green to red 3.3v,
green positive.

 

[Alan Quay]

So green is likely to be battery voltage for display. White is probably floating about, as it signal input, red 5v, black 0v. To confirm check red to black and white to black....

Thank you, that's answered the unknown.
I did spin the front wheel whilst operating the throttle, no result.
To be clear, I connected this to all functions, PAS sensor and throttle, but what threw me was the lack of a selector switch, so my assumption was the controller reacted to the stopping of pedalling and then throttle use.
I have tried only connecting one function, the throttle, but get no LED indication at the throttle that power is present. Power is indicated at the separate display panel. Is this panel only for the PAS system?

You have to turn the pedals for the throttle to work, not the wheel.

Your throttle is: Red 5v, black 0v, white signal, green battery voltage display. If you connected the green to the red or the white, you will have wiped out the throttle.

 

[Alan Quay]

..... If you connected the green to the red or the white, you will have wiped out the throttle.

Its easy to prove if its working: connect the red and blacks from controller to throttle. Stick a meter between white from throttle and black, have someone twist it. Volts will go from around 1-4 (ish)

I have now, with the bike upside down, reconnected the controller as before and turned the pedals and operated the throttle, no motor output.
Checked the voltage of throttle outlet from controller 4.4v. The LED at the throttle does not light up, although the display panel does. The crank sensor is within 2 mm of the magnetic disc on the opposite side to the chain.

I have attached the wiring diagram sent to cover this kit.
It does not show the throttle.
Kit: 36v 290rpm 80mm motor, PAS sensor, Brake sensor, throttle with LED display, display panel, controller, battery 36v 10Ah, wheel assembly with motor.
From the advise above, am I to understand that this controller integrates the PAS and throttle control, in that only when you pedal and the front wheel is turning that the throttle is functional. You do not need a switch to select PAS or Throttle.

Have you tried turning the pedals backwards, in case the magnet ring needs turning over?

Yes tried, wondered what readings from the 3 wires from the controller when detached from the motor, when pedalling?

Now that I can nearly see what you've got, I understand that this is standard stuff. If what you've got doesn't correspond with the diagram, it might be a good idea to show us what you do have, otherwise, instead of help, you'll just get wild guesses. Please take a photo of your connections at the controller, which shows each connector and the wire colours clearly. Please show them connected so that we can see what you've done with each connector. Please check that the photos clearly show what's requested before posting. i get fed up of having to go through several iterations because people can't apply a bit of common sense when posting photos. Please show also a picture of your pedal sensor and throttle.

I have taken images of the control outlet to each device, with the device shown. The throttle to control is cable colours do not match, but only 2 four wire receptacles, the display and the throttle, the display colours match.

I'm going to take a wild guess first now that I can see a HWDS in the background. Try disconnecting your brake sensors first to see if it springs to life. They only go one way round. If you've put it on the wrong end of the cable, it'll work backwards. The red LED on its end indicates that the switch is on and the controller off.

It looks like everything is wired correctly. If you want to test the throttle, connect it and switch the power on. Stick your voltmeter probes up the back of the connector to measure between the black and the white wires. while holding them there, operate (or get someone else to do it) the throttle. At zero throttle, it should be about 1v, which should increase as you open the throttle to 4v at maximum.

You are correct the brake sensor led was lit, as I had it wired. Disconnected it and left all other connections as before. No movement whilst pedalling.
I removed the 4 wire connector from the throttle and connected it to the other 4 wire display connector, the wheel kicked into life without me moving the throttle, ran at a constant rpm. At least I know the motor works.
Have ordered a new controller and throttle, will take another approx. 20 days to arrive. Concluded that I have damaged either or both.
