my car acted up today check gauges came on then auto-theft then service light came on and my gauges dimmed every time i hit the brakes, after a new alternator is works for a while then throws those up again please help

yes all were good and if i could get it somewhere soon i will post the codeDid you check to see if the new alternator is charging?
Did you have the battery recharged and load tested?
Did you check all the battery connections for corrosion?
I had the old one tested put it back in because it tested to be functional but it was still having problemsAre the dash lights still dimming when you hit the brakes?
let me clarify you did have the new alternator tested correct? what voltage is it putting out?
