1996 Ford Taurus 6 cyl Front Wheel Drive Automatic

i had my starter checked at auto zone and it was good and my battery is only about 3 months old we tried to jump start it but the motor turned over very very slow just 2 days ago i could turn the key and it started right up. you can have everything off and take the hot post off and you can see a small ark. should it do that thanks larry[/quote:78d4db4a5f]

Start by load testing the battery. If the battery is fully charged and passes a load test, then the next test is starter draw. While attempting to crank the engine, the voltage should stay at or above 10 volts. Current draw may initially go as high as 350 amps, but should drop back to 125 to 150 while cranking. If this test shows a high draw, check for binding in the engine. If the engine has been overheated, a piston could have scored and be binding. If a head gasket has failed, coolant can hydraulically lock a cylinder.

Also, don't take everything Auto Zone tells you as the gospel truth. After all, who knows more about cars, a professional repair technician or a $7.50/hour parts clerk???
