- Thu Dec 18, 2008 5:37 am #84373 Ok guys I need some insight into this little problem that popped up with my civic this evening. I was driving around and when I stopped at a light the radio cut out, the gauges died and the lights dimmed. So I revved it up to about 1k rpms and everything came back on. So I turned everything I could off and drove home (about 15-20 miles). The problem would only happen at idle, there was no more stops on my way home and the lights stayed nice and bright. So my initial thought was a bad alternator, but I'm not so sure. I'm going to check it out more in the morning, it was very cold out tonight. Any help is appreciated. Thanks

12.5 volts at the batt, car off
14.5 volts high idle
12.5 volts everything on

It didn't die when I disconnected the batt at warm idle, but did die when disconnected w/ everything on. It seems my problem has disappeared, but I'm gonna take a 30 mi ride now w/ my volts gauge and see what happens.

Make sure all your engine grounds are present and in good shape.
