yesterday I was driving on a motorway, at around 115km/h, using cruise control. At some time, electricity suddenly cutted off all power like I would have turned the key to OFF. After 3 seconds everything powered back on, and I could continue drive home. I parked, but after 10 minutes after I wanted to use car again, nothing would happen when I turned the key.
Becouse there's not much I can do, I unplugged the battery at negative pole for a minute. After reconnecting, still nothing would happen. Only after I tried that for 3 times, car would normally start again. Also when I connect the battery, after a couple of seconds, I can hear a loud beep.
Does my car have a alarm?
That brings me to my new question, which could also be a solution
One day before that I have replaced the radio. At the bottom of windshield was a red light in a plastic which I thought, previus owner had for a car phone. I cutted that off, also I cutted off microphone like looking things at both top sides of front windshield. But car worked normally after that.
Could that be the problem, or is this not connected or relavant to alarm!
Thanks for your help!
