One final point for fun that might help if anybody wants to make their final guess before I open the controllers: the voltage on the blue wire is 5.0v. All the sensors have 4.7v on their red wires.

Good suggestion. Interestingly, the same reels were listed as £22 for me, so £11 at half price. Can you check those prices again to see if they're the same?

I'm pretty sure that it's a basic setting that you can change in the LCD, but limited options, like 3, 5 or 9 levels. If you get the programming cable, you can adjust the power for each level as well as set the number of levels.

The speed sensor socket is normally red, white and black. There is one on this controller, and it's the only unused 3-pin connector on the controller. I tried it in case it's for throttle, but no joy. There are a pair of brake connectors elsewhere, so I don't think that's it, though the blue...

Tell your boss to change the brand name. Nobody can say it, let alone remember it to recommend it to anyone. The name should be a single syllable and easy to remember, like "Sprite".

If the problem were the display, it wouldn't work then not work. We need a logical explanation of how that can happen, and there is one that fits, but you need to do a test first to make it completely logical. Is there any way, you can put a voltmeter across the battery wires while you do one...

Please let us know if it works.

When I got to checkout, it said they can't ship to my address, which is my normal shipping address provided by PayPal. If anybody gets success with ordering, please let me know.

Solid is not enough. The outer either reaches the line or it doesn't. Which is it? There are three combinations of the wires that make the motor go forward and three that make it go backwards. Sometimes, there's a bit of asymmetry, so some combinations work better than the other, or a...

These small displays are very difficult to operate unless you have tiny hands. I can't feel where the buttons are when I'm riding, and even when I figure out where they are, I have to sort of press the thumbnail in to get the click. It's not the sort of thing you'd want to be doing every couple...

I'm not sure you can use it as the battery lock unless you have the same type already, but without the wires and switch. You can still use it separately in the positive battery wire, by cutting it and extending it to wherever you can mount the switch.

I bought two KT controllers from Topbikekit at the same time and they arrived in the same box. One of them is the same as any other, but the other has weird throttle wiring, if that's what it is. Normally, the PAS, Throttle and speed 3-pin connectors are all in one bunch. This one is the same...

Can you and anybody else please keep to the thread topic, which supposed to be specifically about the Argos bike. If you want a thread that's general ebike improvements, please start your own. I made good progress today after getting out of hospital yesterday pretty well cured. I will continue...

You can't use a normal 15A switch. The inrush burns the contacts in no time at all. The only ones that gave/give any significant life were/are the key-switches that have sliding contacts. IIRC, they switch on the positive red wire. They're probably only good up to 36v because the inrush from the...

I meant the connector at the motor end of the cable - if you have one. Those Brainpower controllers are very good for compatibility, so I don't think that's going to be the problem, but it's leading me to the possible cause. Did you do the self-learning procedure (also called intelligent...

When I first started with ebikes around 15 years ago, battery switches were not so common, so I made my own to fit between the controller and battery. I did it like post#3 here, and they always worked trouble free. If you read the rest of the thread, it's mainly intellectual masturbation and...

Yes, you can charge through the pins on the multipin connector. I sometimes solder two wires to two pins of one of these things, which you can break to whatever length or number of pins you want. Check that your pins are the more common 2.5mm pitch, otherwise you have to look for pin header with...

I said to make sure the motor connector is in far enough, not to check whether it's old or new. There is a line, which the outer must reach. 1mm short of that line is too far. Which controller and LCD do you have? I've never seen a block connector at the controller end for the three motor phase...

I can't see a slide-hammer working. I'd use a three legged puller.
