Hi. I have an old ebike, basic frame from 2000, modified for lipos and brushless about 15 years ago.
The controller broke recently so I replaced it with a cheap one on ebay with many more wires than I needed.
I also bought a new throttle at the same time, a basic 3 wire one.
I have connected up: the throttle to the controller, the battery to the controller, the controller hall sensor and 3 phase wires to the motor. All other controller connections I've not touched. I felt like it should have just worked but when I turn the throttle nothing happens.
I have a multimeter and have tested the battery wires to the controller are the right voltage.
I've tested the throttle wires and I can't see any voltage on any combination of connections I make with the multimeter probes. Same for the 3 phase wires.
I don't really know how to go about diagnosing this. I sort of assume the controller and throttle are ok as they are new. The motor was sort of turning (stuttering/cogging) with the old controller connected and I figured I had a short somewhere in the old controller.
So I think all the components are working, but don't know what to do next. These are the rubbish instructions I've got:
