2004 ford escape xlt New battery tested alt. (good)Battery light goes off when runningThe battery is not charging even though the alternator working

How do you know the battery is not charging? Did you probe the battery leads with your voltmeter while the engine is on and your getting 14.5 volts? If so, then your right, the alternator is working. If it is lower or closer to 12.4 when the engine is off, the alternator might be spinning, but it isn't charging or working. You'll need to replace your alternator.

I meant if when the engine is on and running and you have a low reading or the same as if the engine is off, you'll need to replace the alternator.

thanks for gettin' back. Yes I did all that. It's not something I would normally do but I wanted to double check, so I disconected the neg batt term while at an idol and the engine quit, which tells me it aint charging.

yes, i have done this correctly. The alt has been bench tested and is good!

Is your alternator OVERcharging? That will cause the light to come on too and kill your battery. HTH. -Jim

I am having the same problem! Did you ever find a solution? The battery is charge and the alternator is new. It still don't charged.. It drain's the battery and eventually dies.. I'm very frustrated with this..I appreciate any info I can get.
