Question

ok, battery died, I'm charging it, try to start and it sets off the car alarm. any idea why this is happening and what i can do?

Answer 1

you probably need to replace the battery. Many places (Sears, Battery Exchange, etc.) will verify that your charging system is working for free as long as you buy your battery from them.

Answer 2

Do not take your car to sears or similar outlets, they have no idea what to do! Look in your area for a specialized electric shop that can properly measure the alternator output and the diode ripple. They can also check your battery, it may cost a little but is money well spend.
