Starts up right away with a jump start, runs fine, park it over night,
go to start it next morning...just makes a clicking sound.
Horn, lights, radio, all work.
Car does have a alarm system and after-market stereo, but has worked
fine with these items since we bought it in the summer.
Thoughts on what we need to start trouble shooting first and/or how to
resolve this problem?
Thanks in advance!
Basic stuff here, have the battery tested, check and tighten cable
connections, have the alternator output checked. See if something is
killing the battery when the engine is not running, if the battery was dead,
without charging it for 3 hours or so, it will not start in the next am.
Just about everything is metric on GM cars starting in the late 70's ...

The "park it over night" sure makes it sound more like a drain on the
battery more than a poor connection. But that's just my view.
I'd pull one line off the battery and put an amp meter in line with the
car shut off to see what the draw on the battery is. The computer takes
very little in "standby". I'm guessing at the number, but I'd worry
about any battery drain over .1 or .2 amps. (make sure the doors are
closed and no interior light is on) My mothers Intrepid (she's a spunky
gal in her mid 70's) had a similar problem, but she didn't tell me the
radio stopped working. 300 miles left on the warranty and a new radio
fixed the the dead battery (that one took 1 to 3 days to go dead
depending on how well it had charged the battery while running).
Does this stereo have one of those giant capacitors often used with sub
woofers? With a heavy wire going from the capacitor directly to the
battery? That is a good place to look for a problem, yes, even if the
stereo works perfect.
If you can't measure the drain on the battery, start by pulling out a
few fuses after shutting it off until you go through them all. The fuse
that stops the battery from going dead leads to the fault/short. I'd
start with the after market radio especially if it has a "super cap".
Hopefully if it has a super cap, it is properly fused! That sucker
could blow your dash apart if it shorted real good!)
Also, an old girlfriends car had a problem with the battery going dead
over night. It was the alarm. Sometime in the middle of the night, it
would turn on or flash the lights until the battery was dead. If it had
activated the siren also, that would have been a LOT easier to figure
out! The car was a POS so I disconnected the after market alarm. The
best thing that could have happened is for it to get stolen, but it
