maybe your voltage dropped to low, and tripped your light on, and it stayed on. turn your car off and back on...and see if it is still on?

12.24 volts is far from a charged battery

12.2x vdc at idle for your average OEM alternator isn't unrealistic, I would say.

uhh a charged battery car on should say 13 at least.

a wet cell fully charged will rest at 12.6v it would need a minimum of 13.5 v to charge it most 12v alts on just about any car i can think of will put out 13.5-14.4 v

My Dodge has a Volt gauge and this is how it works. When the engine is running the altenator keeps the battery at 13.7 volts. Whenever the voltage drops below 12.5 Volts the Voltage gauge drives to zero and the Check Guage light comes on.

In your case I would suspect your altenator is going bad. Unless your battery is shorting I would think a good altenator would hold the Voltage above 12.5 volts.

Good luck

I'd also say check the alternator as you should have more voltage at idle otherwise you'd be lucky to charge your battery while running accessories, etc... Belt could be old/slipping. Check voltage at the alt, not the batt.

Also make sure your battery cables aren't old/corroded...
