I just bought the following kit and battery: https://www.ebay.com/itm/48V-1000W-Electric-Bicycle-Motor-26-Bike-Front-Wheel-Conversion-Kit-Cycling/162293809933, and https://www.amazon.com/gp/product/B07C15TR3T/ref=ox_sc_act_title_1_1_1?smid=AF0FBM1E362GS&psc=1. My stupid thinking I touched the red wire with the black wire and there was a spark. Now the tail light will not go on. Did I do some serious damage to the battery, hub, or controler? Will I have to replace the whole thing? I need help really bad. I dont have a volt meter or anything to test circuits. I think I screwed up big time.
