Asked in Chevy Tahoe
What is killing the battery on a 97 Chevy Tahoe It is brand ne It will not crank in the mornings unless battery is charged?
Bad alternator? May have short, will still charge, but drains the battery when sitting. Just as a test, take one of the battery cables off at night and see if the battery stays charged. Might be bad battery even though new. Hood light that's not shuting off? Brake switch not shutting off? Have you checked the altermator to make sure it's charging 14 amps. May be weak and only charging enough to keep the truck running with nothing left to charge the battery. Out of ideas
