Zero response when everything is hooked up

[Liam.great98]

I hooked up all the parts today and when I turn the throttle, there is no response. The motor doesn't go, there's no noise, nothing. Here's the setup:
Hall effect throttle
24v 250watt controller
Two 12v SLA batteries in series
Key switch
24v 250watt MY1018 brushed motor (mid drive)

The only bad condition was that I tested it in the freezing garage today, where the bike and all the parts (except the batteries) were left. I don't see how a cold controller could cause no response though.
My batteries are fully charged, and I know the motor is good because when I connect it to just a single battery (12v) it runs. I've just got the controller and throttle, so I have no idea if they work, but they were bought new on ebay. My controller has two sets of unlabeled wires, blue/red and black/red. I assumed the black/red was for the battery, and the blue/red was for the motor, which is how I connected it. The throttle had a black, red, and white wire and the controller had a blue, red, and black wire. Both had female plugs so I cut them off and soldered the wires. When they were in the plugs though, the colours didn't line up. The red lined up with the black or something silly, so I connected red to red, black to black, and blue to white. Also, when I hooked up the batteries to the controller there was a small spark blue, but I'm guessing this is typical. When I "ignite" by pushing in and turning the key, and then turning the throttle, nothing happens at all. Nothing gets warm either. Any help would be appreciated.

Check that you have 5v between the red and the black throttle wires when powered up. If, not,disconnect the throttle and try again. If still not, check that you have 24v on the power wires directly into the controller.

Should I check for 5v while the throttle is connected, or disconnect it?

Even before the throttle, I'd look at the key switch. Does it have voltage before the switch, and after? If yes,,

Then look for 5v on the red and black wires of the throttle. While hooked up is fine. If yes, do you get 5v on that blue /white wire? If no on that wire, it's just a bad throttle. If yes, then it looks bad for the controller.

Do be sure your plugs from controller to throttle look good. No contacts backing out of the housings.

you can find the 5V on the red/black in the hall sensors 5 pn plug when the controller is active. make sure you connect the small red wire for the controller circuit current.

Check it disconnected, and then again when it's connected. Obviously if there'es nothing after the first test, there's no point in doing the second.

And the result is?

Brushed motor, so no hall plug..so check for 5 volts on the throttle plug..

So connect only controller to battery..no other connections.
connect the negative of the voltmeter to the negative of the battery.
Now with the red probe of the voltmeter, check each of the three pins on the throttle plug.
one (black more than likely) will be (should be zero)
red should be near on 5 volts..any where from 4.0 up to 6 is good.
the other wire (green?) could be any voltage,..it may well have 5 ish volts on it too.

If you have zero volts on all wires then the controller is not powering up.
you may well have to connect a small red from controller to battery positive too..this wold be an 'ignition' power on wire.

Photos help

post pics of your controller and the wires..if you want to be really helpful, label each wire in Photoshop etc .A B C etc

Looks like dogman had the right idea. After taking a break from working on the bike over the winter, I finally got back to working on it. Brought all the electronics into the house (out of the garage) and shorted the wires from the key switch. Works perfectly. Then if I remove my wire and just have the keyswitch, it doesn't work. So it's just my garbage-quality key switch.
Yay!
