has my alternator packed up?
How would i tell?
Reason i ask is last week i took the car for like a 1.5 mile drive, and on the way back i lost power from the battery, pulled up, tryed starting and i got the famous alarm chirp for low voltage in the battery
now the car has been stood for a while but surly the alternator just 'stopped working' can it?

You would have gotten all the warning lights come up, batt, abs etc if the alternator had gone, plus the car would just stop 
so doubt it will be a battery if that happened.
Is it a new age car?

IMHO (!) dis-claimer....
Security issue, immobiliser cutting the ignition or fuel perhaps ? This could actually be caused by the alternator draining power from the battery....

Local radio transmitters can "jam" your system....
Seriously, if it's on it's last legs it could immobilise the engine, I don't work on them professionally, but it's got to be battery, alternator or electronics.
1. Charge battery
2. Get alternator checked out.
3. Auto-electrician on the alarm side.
Sorry !

Charge the battery and then measure the voltage between it's terminals using a voltmeter. A good battery will be somewhere between 12.6 to 13 volts immediately after charging. Start the car and measure again and you should see an increase in voltage to over 13 volts up to 14 volts if the charging system is working. If not then it could be the alternator itself but is more likely the regulator assembly that converts the AC output from the alternator to DC voltage required.
