Had a result! Made a bit of a mess of several sewing needles, which is a pretty serious matter apparently, but managed to prise the side contacts out in the connectors and all sorted. Tester is interesting but think it would need some adaptors or it's connectors changing. I have an Atlas...

Thanks, MOSFET's ? Incoming neg to each phase is 3.3K ohm, incoming pos to each phase is 6.9 K ohm. The owner is not keen on my suggested options for making any sort of alteration to the cables/connectors, I think he is still hoping cyclotricity may come on-board at some point. So I have been...

Afraid I don't see any MOSFET test details anywhere above and it would seem that something needs to be done about the cables regardless of anything else that might be found. Just had a quick look on ebay and none on the first page appear to have the same connectors as these, but I am not too...

Possibly some progress. Checked the 3 phase connections from controller to the motor and all OK but cant get anything on the +, - or the outputs from the sensors between the controller and motor using the supplied cables. Having trouble finding a reliable way of testing the cables, if I connect...

Got the go-ahead to start dismantling things as the owner is not getting any replies from cyclotricity. I thought it might be easiest to check the hall sensors directly at the motor rather than digging all the sealing bodge out of the controller, the sensors are 41f's and switch on as soon as...

Spoken to the owner and he wants to have cyclotricity sort it if it means taking things apart, he has now decided that it might be under warranty but he's not sure! So thanks for all the help everyone but will have to leave it at that for now.

I haven't been able to get in touch with the owner yet but had a look in the controller and it does not look like getting to the circuit board tracks is going to be possible without leaving evidence of tampering as there is a lot of adhesive at the cable entry end and the owner still seems to be...

I'm finding it difficult to test these, the connector is quite clever the way all the connections are integrated into one plug/socket but from a testing viewpoint it is terrible. The only way I can see is to get into the controller or open the motor up but I will have to see what the owner...

Thanks for the quick reply and info, I hadn't spotted the extra connections to the motor, very neatly placed around the outside of the 3 main connections. There are 7 extra but can't say if they are all in use and haven't time to do anything with it tonight.

Hi, Just regesterd on the site and I don't really know much about ebikes but have some knowledge of electrical systems and have been asked to have a look at a cyclotricity conversion, I believe it is a 1KW motor, which is mounted in the rear wheel. Problems: the motor is quite noisy, there is...
