    Cam battery and HK3 cable connection

    I have A129 Pro Duo FW 2.4 hardwired with HK3 cable. When I set HK3 switch to 12.4v cam hardly operates (all lights off) during Parking mode which I assume HK3 cuts off power supply. Once I switched to 12.2v cam works fine with Parking mode but my car shows low battery warning from time to time...
