There is another, current Post, addressing the same symptoms. Yours also sounds like a CPS going bad.

If you haven't replaced the OEM black one.. replace it with "Ford recall" Grey one..

Yes.. You should see 14.5+ volts, but not more than 15v, when the engine is Running. Engine off, you should see 13+ volts. If you've been cranking it.. you may need to Charge the batteries ?
