Hello, I'm new to the ebike community. I recently baught a 1000w bbshd and a whale shark 52v 21ah battery from bafang usa direct. I tested it before I put it on my bike and I noticed that the battery connector sparked when I attached it. Despite this it worked good. I unplugged it and installed it to my bike. This time no there was no spark and it won't go on. I tested for continuity from the negative and positive terminals where the battery goes and the circuit is completed there. I'm not sure where else to test. Please help!!!
