My car it what stay charging start it up and
10 15 the Votage light come on but u punch
it all the way down and the light goes off
your question is hard to understand, but Ill take a swing at it. start the car and put a multimeter on the battery on volts dc. car running, it should read over 14 volts. if much less than that then you likely have a bad alternator.
