5.0L (1979-1995) MustangTechnical discussions on 5.0 Liter Mustangs within. This does not include the 5.0 from the 2011 Mustang GT. That information is in the 2005-1011 section.
I tried to start my car yesterday and it was dead.. All it make was a fast paced tick noise. I jumped the battery and the car ran great. Let it run for about 10 mins. I turned it off and tried to start it again and it was dead again. I just replaced the voltage regulator a few weeks ago and took the alternator to Kragen and they said it was fine. Maybe the battery itself is shot?
Check to see if the car is charging the battery. An easy way but not 100% way to tell is with a voltmeter. Should be about 12.6 with the engine off and 13 or 14 volts while it's running.
Take it to NAPA and have them test the battery, if you have another car you should be able to drop it off. they will load test it and charge it for you, Advanced, AutoZone and PepBoys also do the same.
Guess so.. I just put the battery in the car after charging for 24 hours and it didnt even start at all.. Just dead. I put it back on the charger now its completely dead again. i guess that confirms it.
My neighbor owns a bunch of brand new batteries from his job so ill get one off him for 30 bucks
