Disconnect the negative side of the battery. Hook a volt meter on the negative cable end, and hook the positive end of volt meter on the negative post of battery See what it reads. If it reads 12 volts, pull fuses one by one, and replace until the volt meter drops down. Whatever fuse you pull, and the voltage drops down to 2 volts, that is where the problem lies.

2002 mercury cougar make a clicking noise like the battery is dead but it's not and won't jump start either.


Are you sure the battery is not dead? This is usually a good indicator of a dead battery or not enough charge to turn it over
Failing that Loose leads,Poor connection to starter motor or faulty starter motor.

If you get no red light for the battery charging system the charging system will not work. The indicator light initally excites the field to start charging.

It is dead had battary charger on all night stillnothing 91 cougar xr7 i know its some thing ele


Even at a 2amp charge over 12hours, your battery should be at or near full charge. Battery is likely bad. When charging, was the battery still connected to the car and, what was the actual charging rate?

Check for bad relays, that get stuck. Some fuel pump relays get stuck also. Make sure nothing is left on such as any lights , etc. Your alternatopr could be bad too.
