After 24 hours car will not crank with perfectly fine battery. No gauges left on, no headlights left on, nothing known to be drawing current. Any suggestions?

Thanks
 
I had a car alarm on my car that was draining my battery.How long since you drove car?The clock on radios will kill battery if it sits a little while.Was told if you drain a battery dead it loses half life.Maybe try new battery.I remember reading once that the fans sometimes will come on without car running.I think it was bad relay.
 
Common problem with TRs is the speedo case is not making contact with the plug behind it. If your volt lite does not come on with the key turned on, your alternator will not charge your battery. Be sure your volt lite is on when key is on.
 
Antenna

my power antenna was killing my battery. when it went down, it never stopped trying to go down. current draw stopped when I unplugged it...
 
if u have a volt meter u can do a parasitic draw test. make sure all power is off, meanings doors shut and underhood bulb removed, remove negative battery terminal, connect voltmeter in series between cable and battery, have meter set to 10Amp setting. after doing that let the car sit for a few minutes and check the meter for any amperage draw. if there is draw( over .030Amps) start pulling fuses from under the dash one at a time until the draw disappears. this will atleast get u started as to where u need to look!

since the fuses are inside the car u will probably have to disable the interior lights some how, like remove that particular fuse before setting up draw test or maybe taping down the interior lights switch that the door contacts to the left of the dash. u dont want to blow any fuses in the multimeter!hope this helps!
