Q: Battery drains when coming to a stop

asked by on February 18, 2017

When coming to a stop my battery gage will go down and my lights will go dem even when it is just idling then goes back to normal when I hit the gas. First you would think it was the alternator, So I changed the alternator and put in a brand new battery and didn't help the problem, and since the battery will drain while idling I changed the idling sensor and still no change. Have no clue what the problem is.
My car has an automatic transmission.
