You won't see any power out of the phase wires because they're AC. The controller needs to get feedback from the motor to time the pulses, so won't do much without the motor connected and turning.

It's a shame you jumped so far ahead because there were other easier, more reliable and better options.

From the photos, I can't see all the wires from the controller. You need to lay them all out so that we can see all the wires and connectors at once.

Please provide us a link to which conyroller you bought.

Quick update..... When I turn the throttle..... The motor now makes a noise..... But the wheel does not turn...... I did some fiddling and this is progress..... What could be making the throttle work, motor makes noise but no turning? I am sensing this is now a voltage/power problem? Only voltage thing that has changed is that bike shop that spent a week with it and then gave it back changed fuse in battery to a 10amp!

Be very careful about opening the throttle. Only open it about 1/4 otherwise you can damage the controller. You need to get the motor running smoothly before you can fully open the throttle.

You asked me for my help, but you don't do what I suggest, you just keep jumping ahead.

I'm so sorry..... I'm struggling between looking after the kids, cooking and bike in bits in middle of floor! So opening the throttle a little bit starts a motor noise but no turn in wheel..... What's the next step?

Knowing what controller make and type would help.

It's a generic 24v one from eBay as was only small one I could find.

Read what I wrote and do it.

I had another think too. We need to know what went wrong with your last controller. They don't burn out for no reason. Can we see a picture of the burnt bits.

There seemed to be some oxidisation inside the unit.... And white crusty powdery stuff on parts of the inside of casing...... Possibly wet?

There is a burnt area at the top of the controller so for your case I would use another one and try again

Very hard to get a pic of all wires. I have not used the three speed controller, speed limiter and connected the ignition ones together.

This is the replacement I am trying to fit

That's better. It looks like your phase wires have been over-loaded, which probably means that you've damaged the phase wires where they come out of the motor - maybe inside the insulation. Don't use the motor until you've tested the phase wires. You need a meter to test them.

Set the meter onto beep. Test between each phase wire and the motor case. Wiggle the wires a bit where they exit the axle. If any beep, there's a problem. The next test is to put the meter onto low volts AC; put the probes on any pair of phase wires and turn the motor backwards. You should see the meter kich because the motor will work as a generator. Each pair of phase wires should generate. If any don't, there's a problem.

Is it possible to see the other side of the controller to see which components burned?
