Newbie needing help

[Baz24383]

Hi all, Carrera vengeance 2.0 owner here (not by choice, it was a gift). I've managed to solve all problems I've had with the bike in the 2 years I've had it so far but this one as got me stumped. There is no assist coming from the motor at all. There's no error codes showing, walk assist is working, the battery is charging and turning on the lcd display. The crank sensor looks good and is pretty new. Any ideas
Thanks in advance.

What do you mean by "looks good"? Did you take it off and inspect it. Did you look at the light sensors inside to see if they're clean? Did you check at both ends that the wires haven't been pulled?

Yeah, mate. I've done everything you said. The sensors were clean and the wires looked as they should.

Yeah, mate. I've done everything you said. The sensors were clean and the wires looked as they should.

In that case you can check its function with a meter. IIRC, black and red are 5v power, and the two others (assuming that yours is the 4-wire version) are one pulsing 5v when the pedal turn and the other variable voltage between 0-5v depending on how hard you twist the crank. I'm pretty sure that you can get your probes up the back of the connector to check, otherwise I'd have to ask myself how I know what's on those wires.

You should also check the motor connector. some are a bit tight on the wires, so either a wire can pull out or the whole connector can move apart.

Ok mate, thanks for the advice. I'll check them and let you know how i get on
