I started a thread called "Strange Problem" in the General Tech forum. I had been complaining about a bad idle in that thread. Well now my car won't start, it won't even turn over. I've tried jumping the car with no results. I have a yellow top Optima battery. My alternator tested out @ 14V a couple of weeks ago. The oil pressure light, battery light and check engine light in the gauge cluster are very dim with the key in the "ON" position. However my radar detector still works and lights up normally when I turn the key to the "ON" position (radar detector is plugged into the cigarette lighter). My headlights won't turn on...when I attempt to turn them on, my radar detector cuts off...then comes back on when I turn the lights off. I hear a "clicking" under the dash on the driver's side. Sounds electrical. I have heard that it could be a bad main relay or ignition switch. I have no idea exactly what a main relay or ignition switch looks like. Could my idle problem be related to my car not starting/turning over.
