I've been using the K1 since I got it in Dec 2016. Installed on my bike, a Daelim Daystar 125cc cruiser. I've had to change the power box, and dvr on two separate occasions - the latest being the dvr which I managed to burn out on May 20. Everything was working fine for a while, no issues, then I noticed something: 1. connections all correct. 2. battery not charging so barely any standby power in parking mode. 3. video interrupts every time I horn. I'm not sure if it's EM interference from the horn, cos I moved the horn away from the front cam and it still interrupts. Could it be inadequate shielding of the cables? Excessive power drain to the horn? What I've tested is that no interruption occurs if the front cam is disconnected. Any ideas? Thanks in advance!
