Electrical Warning - 2000 Concorde XL

While pulling into a parking lot this afternoon, it appeared my engine
stalled while moving (dash lights came on: oil, AB traction or whatever). I
put the care in neutral and reved the engine. It was running. Shut it off,
attempted to restart, didn't start right away, turned key off then on
again... started. Parked.

The drive home was uneventful until I got off the freeway and close to my
house. Started hearing a "thump" in the right front speaker as the radio
played. Turned radio off then on. Thump. Pulled in drive and shut 'er down.
Repeat of the symptomes in the parking lot... but the car started.

Anyone have any idea what's going on here? I believe there's a diagnostic
test I can run to get a code but I've forgotten the basics. Do have an
official service manual though. Can someone please point me in the right
direcetion to get an idea of what's going wrong?

 

Did you get a "no bus" message in the odometer window? If not, then it
sounds like your battery is on the way out (typical symptoms of failing
battery in the LH cars).

Especially if the battery is the original, you need to replace it
*ANYWAY* - being a 2000, you're running on borrowed time. That will
probably fix the problem, but if not, you really need a new battery to
keep from getting stranded at some inopportune time irrespective of the
symptoms you are reporting. If a new battery doesn' fix it, then pursue
the cause of what your seeing later, but will not have lost a thing
replacing the battery first because you're way overdue - but I bet a new
battery will fix it.

Thanks, Bill. I'll get a new battery.
