Let me set the scene. This past weekend wife and I took a weekend trip and we took the Marauder. No issue driving to our location. And no signs/symptoms of any issues.

Well we woke up yesterday and as we are packing up the car to go home, I noticed that my radio was on an AM station when I started my car and the clock was off . I always have my clock set at the correct time and I always turn my radio off before I turn my car off. It's just a force of habit. Immediately this set off warning bells in my head, because the only time this would happen is if I unhook the battery. Usually when you take the battery off and put it back on, the radio will always be on. So it was weird, but I had no issues going home. Stopped a couple times to take pictures on the way home and I had no issues starting back up or anything.

Fast forward this morning. Went out to the garage to go to work. As soon as I open my driver's side door, all the lights go off. Everything. No interior lights at all. Put the key in the ignition, nothing. No sound. Get out. Open the hood. check all my battery connections. Everything is tight. Open up the door again. My lights are back on. Car fires right up.

I haven't had a chance to dig into this too far, but what kind of symptoms am I having? What will make the car go completely "dead" for about 30 seconds to a minute?

Is this a PATS issue? Fuse issue? Wiring? My battery connections are tight. Maybe I need to shine them up? I don't notice any corrosion built up. Battery is about 2 years old.

How old is the battery?

Check all the power and ground connections under the hood.... everything should be clean and tight.

Look at the condition of the power and ground cables. Is there any corrosion near the ends?

Take the battery to a FLAPS and have them test it.

+1 on battery issues.

Although you have not have not had any issues starting which makes the battery issue a little unlikely.

The lighting issues sound like an LCM, but it certainly would not effect the radio station or clock.

LCM came to mind but you should still be able to start your car. This was as if I didn't have a battery connected at all. Just dead.

FBM battery will be 3 yrs old in July. I cleaned and shined up the connections. All my ground wires look fine. No corrosion or kinks. If the symptoms keep occurring I will take it to a FLAPS and have them check the battery

Can't stop the signal

A battery that is on it's way out or has a cell going bad will give you strange symptoms.

I might stop at a FLAPS tomorrow on my way home from work and get it tested.

I would load test the battery it sounds like it may have a dead cell.

Yeah I'm pretty certain it's the battery. Thanks for all the replies. I will be looking into getting a new one soon.

I'll even give ya eight dolla for it. Don't want you and Michelle stranded out in Washington state with a dead battery! :coolman:
