I've been reading multiple thread but could not find one that suggests anything I have not already tried.
I have a Crystalyte 4012/409 hub and a controller for it. As a dual winding hub, the controller has a switch to determine which of the two windings it will use so its not built into the controller. There is a button for "reverse" that goes onto the board. Otherwise it looks like a relatively standard controllers (pics below) with 8 FETs, caps are 160v, looks like 5 Hall/phase wires (cyan, green yellow black red), 2 three-wire brake connectors, one throttle, reverse button and on/off switch connector. I'm hoping someone will have some ideas why its not working or tell me what type of controller I'll need to replace it.
Here are my observations:
When I hook up power from battery (53v input), the connectors do their normal little sparking as I connect and it light ups normally, but the the LED dies out over 1-2 seconds and by the time I grab a meter and measure the voltage its ~2.5 or 3v. I measured both inside where the power connects to the main board, and the connector from the BMS. This made me think it might be trying to draw to much current.
I've Tried bypassing the BMS and it lights up does not dim, Voltage stays at 53v inside where it connects to main board, and at the battery connector. However, when I turn the throttle, the motor does not engage. I've tried disconnecting the brake connectors, no difference.
If you have ideas I'm quit capable of measuring things inside the controller, but don't know enough about designs to know what I should be trying to do. Place to read more also appreciated.
