The battery died on my 03 diamante. when i tried to recharge it the car alarm started and wont stop to allow the car to keep a charge?

The battery needs to be replaced or the alternator is bad. I would try to replace the battery in your car first to see if that fixes the problem. If our car is still not starting up or if the battery keeps on needing to be recharge then the alternator is bad and should be replaced.

Stick your key in the ignition and turn to start. That should stop the alarm. However, it sounds like your battery still isn't fully charged. Computer things go haywire when battery voltage is 9.6 volts or less.

if its smoking thats a shorted system..if you feel safe with fixing it do so otherwise get rid of that deathtrap..

When the alarm sounds, turn the key to the RUN (NOT START) position, then OFF - do this 10 times rapidly.
Many alarms will turn off and allow the car to start with this method.

It can be any of the car doors not got properly locked or the door is locked but the switch is not sensing the door locked. Open and close each door again properly.

Or else its problem with any of switch wiring getting in contact with alarm wiring causing it to happen.

And last thing alarm connections need to be inspected. It's getting short somewhere in between.

There are few help links with solutions, to troubleshoot these types of problems. I suggest going through these links.

Thanks.

get the battery and charging systmem checked to begin with. A low battery causes issues

Yes, it is likely an alternator since the battery light goes on when the alternator is not charging.

Good luck on this one.

try pulling the fuse from the alarm

Sounds like you have a shorted wire causing a drain. I recommend disconnecting the alarm all together which should stop the short so battery can remain fully charged.

The alternator is what keeps your car running once it's cranked. It also recharges the battery for the next crank. It's either your alternator can't produce enough power to keep the car running. Your fuel filter is dirty. Your air filter isn't allowing air flow. If it sputters before it dies it could also be the O2 sensor.
