So my kit is bbs02b with hailong downtube battery, dpc18 monitor.
Recently i got an "error code 30 communications error" and then i disconnected the harness wire (green) and reconnected it. It no longer turned on. I went back home and i checked the harness and one pin was twisted (on my reconnection trial). So i untwisted the pin and after that nothing works.
The issue was caused by wear and tear on the plug, it was not very tight, but i programmed the controller earlier so there was alot of plugging and unplugging. Also i move my bike in elevator often so the plug could have been too tight at times (which is my error at assembly).
I bought 2 new main cable harnesses from ebay, and got another dpc18 for testing purposes, and the dpc18 still does not turn on. So I checked the battery input and input connections with multimeter, they are fine so the motor gets power. I figured that either both of the new main cable harnesses are broken on arrival or the controller has blown. But then I read somewhere that even if controller is blown dpc18 should still turn on and now I am confused. If power goes in, why does my (confirmed working) dpc18 not turning on?
2000km was ridden before this
