So I replaced the battery in my x8 4x4 800 quad, and ever since I’ve done so my ignition won’t turn on, it’s got no life into it what so ever as if a fuse has blown or something. But all the fuses seem fine. No display lights no nothing. Any ideas what it could be for the quad to be like this? I’ve even tried putting a battery pack onto the battery whilst it’s connect to get a jump start but still nothing. Any help would be appreciated
