You need to get yourself a cheap digital voltmeter so that you can check charging voltage. It should be close to 14 volts. Also a repair manual, does the car have an external voltage regulator? If so, change it and check again. Check that the belt is tight! If you have a new alternator and regulator and no charging, it's likely a wiring problem or blown fuse. Scour the wiring diagram and your fuse box(es) for a "charging" fuse.

    Bloody hell, I forgot, the British probably call it a "dynamo" fuse :-)

could very well be the starter. in some caese the starter will work fine until it gets hot and in some cases it just simply goes out. might have someone tap the starter while trying to start it and if it does then this would indicate bad starter...good luck

My wife dropped the kids off in her lincoln MKZ, then went to the gas station to get gas. When she went to start the car it would start and nothing happened. When I got there someone was jumping the car...


It is very possible for the battery to just die even when the car is running and charging properly. Batteries have a designed working life but that is normally a guide. Some will be replaced during waranty period while other work for 4 years. It would be a good idea though to check for any shorting that might cause the battery to go flat, the charging system itself and a disconnecte lead from alternator to battery.

go again to the dealer or at any gm service center with complete tools and computer diagnostics, by using tech2 find out all the code history, and freeze frame failure record. if no diagnostic code read, there are some program that delete or disabled that cant read by the diagnostic, hptuners will help you for that, read the vehicle data by hp tuners and reset it to original program, review all dtcs that cancelled specially to charging syatem, after reseting, diagnose it again and you can read the trouble codes to perform in rapair

Car will not stay on after I JUMP START


Just try to keep the gas and drive for at leat 15 min HWY if possible. Yes, it will turn off if you let go the gas, but it will restart and stay on as long as you press on gas. Just keep on driving and the computer will readjust the emission inputs and will get back to normal.
