Check ground circuit
You cross the battery.
Change the abs motor.
Most likely cable running from stud on top of alternator to battery terminal is corroded or broken.
Remove the Negative (black) battery terminal while the vehicle is running and if the vehicle dies then it's the alternator, if it stays running then it's the battery. Although this method isn't guaranteed it's usually accurate. DO NOT REMOVE THE POSITIVE terminal (red) from the battery while it's running. It could cause a spark and make the battery explode. Another way is to drive to Autozone or Advanced Auto and ask them to test it. They'll do it for free.
Disconnect the negative terminal of the battery Leave it disconnected for an hour. (The amount of time it takes to replace the battery). Reconnect the negative terminal of the battery. This works because a transient (voltage spike, noise) is generated when the terminal is reconnected. This is not necessary when the battery is replaced because the negative terminal is normally the last connected. However, when a car's battery dies in storage for example and is recharged with disconnecting the battery, the car might not start because the computer is not running.
I have a 1995 Ford Explorer , and with the engine running a mechanic disconnected both battery cables and it kept running - I was surprised!
Have you checked the alternator?
The battery does not have sufficient voltage to start the car when it's cold. Have the battery checked out. If it still goes click click after running the car for a while, have the alternator checked also. A bad battery will not hold a charge and a bad alternator will not recharge the battery, (That is the reason to have the battery checked first). Make sure the connections at the battery are clean and tight.
Power does not go to the battery, it comes from the battery, except when the car is running. At that time power does go to the battery from the alternator. Disconnect the + battery terminal.
Both posts are gray, positive has a red wire running to it, and a plus sign next to it.
with the car running disconnect the negative terminal from the battery if engine dies alternator is no good
Get your charging system checked out as it sounds like your alternator is going bad or the battery is shot.
