Disconnecting the negative terminal on the battery for 2 minutes will reset the check engine light, but if the problem that caused it to turn on originally still exists, it will come on again.

Disconnect the battery. BUT you should have it checked. There's a code stored in memory that is needed to fix the cause of the check engine light being on. If you do the battery thing, don't take it to a service tech and say fix it until the light comes back on.

How can you know if alternator not charging?
thats not really a good recomendation to give,unplugging the battery while the engine is running can cause internal damage to the altenator.its easier testing it with a voltage meter and check the alt and batt indiviually without any unplugging if it reads anywhere between 14.2 to 14.9 ur fine.hope this sounds better and safer... one way to check is while the car is started unhook the battery if the car stay started its not the altenator
